cvs commit: httpd-2.0/docs/manual/mod mod_auth_ldap.xml mod_auth_ldap.html.en index.html.en directives.html.en mod_auth_ldap.html
slive 2002/08/30 14:07:44
Modified: docs/manual/mod index.html.en directives.html.en
Added: docs/manual/mod mod_auth_ldap.xml mod_auth_ldap.html.en
Removed: docs/manual/mod mod_auth_ldap.html
Log:
Convert mod_auth_ldap to xml. This doesn't quite conform
to the DTD because there are some <font> tags that need to
be removed. There are a bunch of other little things
that could be improved, including adding proper
<description> tags.
Mod_ldap still needs to be converted.

<summary>
<p><module>mod_auth_ldap</module> supports the following features:</p>
<ul>
<li>Known to support the <a
href="http://www.openldap.org/">OpenLDAP SDK</a> (both 1.x
and 2.x), and the <a
href="http://www.iplanet.com/downloads/developer/">iPlanet
(Netscape)</a> SDK.</li>
<li>Complex authorization policies can be implemented by
representing the policy with LDAP filters.</li>
<li>Support for Microsoft FrontPage allows FrontPage users to
control access to their webs, while retaining LDAP for user
authentication.</li>
<li>Uses extensive caching of LDAP operations via <a
href="mod_ldap.html">mod_ldap</a>.</li>
<li>Support for LDAP over SSL (requires the Netscape SDK) or
TLS (requires the OpenLDAP 2.x SDK).</li>

<p>There are two phases in granting access to a user. The first
phase is authentication, in which <module>mod_auth_ldap</module>
verifies that the user's credentials are valid. This also called
the <em>search/bind</em> phase. The second phase is
authorization, in which <module>mod_auth_ldap</module> determines
if the authenticated user is allowed access to the resource in
question. This is also known as the <em>compare</em>
phase.</p>
<section id="authenphase"><title>The Authentication
Phase</title>
<p>During the authentication phase, <module>mod_auth_ldap</module>
searches for an entry in the directory that matches the username
that the HTTP client passes. If a single unique match is found,
then <module>mod_auth_ldap</module> attempts to bind to the
directory server using the DN of the entry plus the password
provided by the HTTP client. Because it does a search, then a
bind, it is often referred to as the search/bind phase. Here are
the steps taken during the search/bind phase.</p>
<ol>
<li>Generate a search filter by combining the attribute and
filter provided in the <directive module="mod_auth_ldap"
>AuthLDAPURL</directive> directive with
the username passed by the HTTP client.</li>
<li>Search the directory using the generated filter. If the
search does not return exactly one entry, deny or decline
access.</li>
<li>Fetch the distinguished name of the entry retrieved from
the search and attempt to bind to the LDAP server using the
DN and the password passed by the HTTP client. If the bind is
unsuccessful, deny or decline access.</li>
</ol>
<p>The following directives are used during the search/bind
phase</p>
<table>
<tr>
<td><directive module="mod_auth_ldap">AuthLDAPURL</directive></td>
<td>Specifies the LDAP server, the
base DN, the attribute to use in the search, as well as the
extra search filter to use.</td>

<td><directive module="mod_auth_ldap">AuthLDAPBindDN</directive></td>
<td>An optional DN to bind with
during the search phase.</td>

<td>An optional password to bind
with during the search phase.</td>

</section>
<section id="authorphase"><title>The Authorization
Phase</title>
<p>During the authorization phase, <module>mod_auth_ldap</module>
attempts to determine if the user is authorized to access the
resource. Many of these checks require
<module>mod_auth_ldap</module> to do a compare operation on the
LDAP server. This is why this phase is often referred to as the
compare phase. <module>mod_auth_ldap</module> accepts the
following <directive module="core">Require</directive>
directives to determine if the credentials are acceptable:</p>
<ul>
<li>Grant access if there is a <a href="#requser"><code>require
valid-user</code></a> directive.</li>
<li>Grant access if there is a <a
href="#reqgroup"><code>require user</code></a> directive, and the
username in the directive matches the username passed by the
client.</li>
<li>Grant access if there is a <a href="#reqdn"><code>require
dn</code></a> directive, and the DN in the directive matches
the DN fetched from the LDAP directory.</li>
<li>Grant access if there is a <a
href="#reqgroup"><code>require group</code></a> directive, and
the DN fetched from the LDAP directory (or the username
passed by the client) occurs in the LDAP group.</li>
<li>otherwise, deny or decline access</li>
</ul>
<p><module>mod_auth_ldap</module> uses the following directives during the
compare phase:</p>
<table>

<td>The attribute specified in the
URL is used in compare operations for the <code>require

<section id="requiredirectives"><title>The require Directives</title>
<p>Apache's <directive module="core">Require</directive>
directives are used during the authorization phase to ensure that
a user is allowed to access a resource.</p>
<section id="reqvaliduser"><title>require
valid-user</title>
<p>If this directive exists, <module>mod_auth_ldap</module> grants
access to any user that has successfully authenticated during the
search/bind phase.</p>
</section>
<section id="requser"><title>require user</title>
<p>The <code>require user</code> directive specifies what
usernames can access the resource. Once
<module>mod_auth_ldap</module> has retrieved a unique DN from the
directory, it does an LDAP compare operation using the username
specified in the <code>require user</code> to see if that username
is part of the just-fetched LDAP entry. Multiple users can be
granted access by putting multiple usernames on the line,
separated with spaces. If a username has a space in it, then it
must be the only user on the line. In this case, multiple users
can be granted access by using multiple <code>require user</code>
directives, with one user per line. For example, with a <directive
module="mod_auth_ldap">AuthLDAPURL</directive> of
<code>ldap://ldap/o=Airius?cn</code> (i.e., <code>cn</code> is
used for searches), the following require directives could be used
to restrict access:</p>
<example>
require user Barbara Jenson<br />
require user Fred User<br />
require user Joe Manager<br />
</example>
<p>Because of the way that <module>mod_auth_ldap</module> handles this
directive, Barbara Jenson could sign on as <em>Barbara
Jenson</em>, <em>Babs Jenson</em> or any other <code>cn</code> that
she has in her LDAP entry. Only the single <code>require
user</code> line is needed to support all values of the attribute
in the user's entry.</p>
<p>If the <code>uid</code> attribute was used instead of the
<code>cn</code> attribute in the URL above, the above three lines
could be condensed to</p>
<example>require user bjenson fuser jmanager</example>
</section>
<section id="reqgroup"><title>require group</title>
<p>This directive specifies an LDAP group whose members are
allowed access. It takes the distinguished name of the LDAP
group. For example, assume that the following entry existed in
the LDAP directory:</p>
<example>
dn: cn=Administrators, o=Airius<br />
objectClass: groupOfUniqueNames<br />
uniqueMember: cn=Barbara Jenson, o=Airius<br />
uniqueMember: cn=Fred User, o=Airius<br />
</example>
<p>The following directive would grant access to both Fred and
Barbara:</p>
<example>require group cn=Administrators, o=Airius</example>
<p>Behavior of this directive is modified by the <directive
module="mod_auth_ldap">AuthLDAPGroupAttribute</directive> and
<directive
module="mod_auth_ldap">AuthLDAPGroupAttributeIsDN</directive>
directives.</p>
</section>
<section id="reqdn"><title>require dn</title>
<p>The <code>require dn</code> directive allows the administrator
to grant access based on distinguished names. It specifies a DN
that must match for access to be granted. If the distinguished
name that was retrieved from the directory server matches the
distinguished name in the <code>require dn</code>, then
authorization is granted.</p>
<p>The following directive would grant access to a specific
DN:</p>
<example>require dn cn=Barbara Jenson, o=Airius</example>
<p>Behavior of this directive is modified by the <directive
module="mod_auth_ldap">AuthLDAPCompareDNOnServer</directive>
directive.</p>
</section>
</section>
<section id="examples"><title>Examples</title>
<ul>
<li>
Grant access to anyone who exists in the LDAP directory,
using their UID for searches.
<example>
AuthLDAPURL ldap://ldap1.airius.com:389/ou=People, o=Airius?uid?sub?(objectClass=*)<br />
require valid-user
</example>
</li>
<li>
The next example is the same as above; but with the fields
that have useful defaults omitted. Also, note the use of a
redundant LDAP server.
<example>AuthLDAPURL ldap://ldap1.airius.com ldap2.airius.com/ou=People, o=Airius<br />
require valid-user
</example>
</li>
<li>
The next example is similar to the previous one, but is
uses the common name instead of the UID. Note that this
could be problematical if multiple people in the directory
share the same <code>cn</code>, because a search on <code>cn</code>
<strong>must</strong> return exactly one entry. That's why
this approach is not recommended: it's a better idea to
choose an attribute that is guaranteed unique in your
directory, such as <code>uid</code>.
<example>
AuthLDAPURL ldap://ldap.airius.com/ou=People, o=Airius?cn<br />
require valid-user
</example>
</li>
<li>
Grant access to anybody in the Administrators group. The
users must authenticate using their UID.
<example>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid<br />
require group cn=Administrators, o=Airius
</example>
</li>
<li>
The next example assumes that everyone at Airius who
carries an alphanumeric pager will have an LDAP attribute
of <code>qpagePagerID</code>. The example will grant access
only to people (authenticated via their UID) who have
alphanumeric pagers:
<example>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid??(qpagePagerID=*)<br />
require valid-user
</example>
</li>
<li>
<p>The next example demonstrates the power of using filters
to accomplish complicated administrative requirements.
Without filters, it would have been necessary to create a
new LDAP group and ensure that the group's members remain
synchronized with the pager users. This becomes trivial
with filters. The goal is to grant access to anyone who has
a filter, plus grant access to Joe Manager, who doesn't
have a pager, but does need to access the same
resource:</p>
<example>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid??(|(qpagePagerID=*)(uid=jmanager))<br />
require valid-user
</example>
<p>This last may look confusing at first, so it helps to
evaluate what the search filter will look like based on who
connects, as shown below. The text in blue is the part that
is filled in using the attribute specified in the URL. The
text in red is the part that is filled in using the filter
specified in the URL. The text in green is filled in using
the information that is retrieved from the HTTP client. If
Fred User connects as <code>fuser</code>, the filter would look
like</p>
<example>(&<font
color="red">(|(qpagePagerID=*)(uid=jmanager))</font>(<font
color="blue">uid</font>=<font
color="green">fuser</font>))</example>
<p>The above search will only succeed if <em>fuser</em> has a
pager. When Joe Manager connects as <em>jmanager</em>, the
filter looks like</p>
<example>(&<font
color="red">(|(qpagePagerID=*)(uid=jmanager))</font>(<font
color="blue">uid</font>=<font
color="green">jmanager</font>))</example>
<p>The above search will succeed whether <em>jmanager</em>
has a pager or not.</p>
</li>
</ul>

<section id="usingtls"><title>Using TLS</title>
<p>To use TLS, simply set the <directive
module="mod_auth_ldap">AuthLDAPStartTLS</directive> to on.
Nothing else needs to be done (other than ensure that your LDAP
server is configured for TLS).</p>
</section>
<section id="usingssl"><title>Using SSL</title>
<p>If <module>mod_auth_ldap</module> is linked against the
Netscape/iPlanet LDAP SDK, it will not talk to any SSL server
unless that server has a certificate signed by a known Certificate
Authority. As part of the configuration
<module>mod_auth_ldap</module> needs to be told where it can find
a database containing the known CAs. This database is in the same
format as Netscape Communicator's <code>cert7.db</code>
database. The easiest way to get this file is to start up a fresh
copy of Netscape, and grab the resulting
<code>$HOME/.netscape/cert7.db</code> file.</p>
<p>To specify a secure LDAP server, use <em>ldaps://</em> in the
<directive module="mod_auth_ldap">AuthLDAPURL</directive>
directive, instead of <em>ldap://</em>.</p>
</section>
<section id="frontpage"><title>Using Microsoft
FrontPage with mod_auth_ldap</title>
<p>Normally, FrontPage uses FrontPage-web-specific user/group
files (i.e., the <module>mod_auth</module> module) to handle all
authentication. Unfortunately, it is not possible to just
change to LDAP authentication by adding the proper directives,
because it will break the <em>Permissions</em> forms in
the FrontPage client, which attempt to modify the standard
text-based authorization files.</p>
<p>Once a FrontPage web has been created, adding LDAP
authentication to it is a matter of adding the following
directives to <em>every</em> <code>.htaccess</code> file
that gets created in the web</p>
<example><pre>
AuthLDAPURL the url
AuthLDAPAuthoritative off
AuthLDAPFrontPageHack on
</pre></example>
<p><directive
module="mod_auth_ldap">AuthLDAPAuthoritative</directive> must be
off to allow <module>mod_auth_ldap</module> to decline group
authentication so that Apache will fall back to file
authentication for checking group membership. This allows the
FrontPage-managed group file to be used.</p>
<section id="howitworks"><title>How It Works</title>
<p>FrontPage restricts access to a web by adding the <code>require
valid-user</code> directive to the <code>.htaccess</code>
files. If <directive
module="mod_auth_ldap">AuthLDAPFrontPageHack</directive> is not
on, the <code>require valid-user</code> directive will succeed for
any user who is valid <em>as far as LDAP is
concerned</em>. This means that anybody who has an entry in
the LDAP directory is considered a valid user, whereas FrontPage
considers only those people in the local user file to be
valid. The purpose of the hack is to force Apache to consult the
local user file (which is managed by FrontPage) - instead of LDAP
- when handling the <code>require valid-user</code> directive.</p>
<p>Once directives have been added as specified above,
FrontPage users will be able to perform all management
operations from the FrontPage client.</p>
</section>
<section id="fpcaveats"><title>Caveats</title>
<ul>
<li>When choosing the LDAP URL, the attribute to use for
authentication should be something that will also be valid
for putting into a <module>mod_auth</module> user file. The user ID is
ideal for this.</li>
<li>When adding users via FrontPage, FrontPage administrators
should choose usernames that already exist in the LDAP
directory (for obvious reasons). Also, the password that the
administrator enters into the form is ignored, since Apache
will actually be authenticating against the password in the
LDAP database, and not against the password in the local user
file. This could cause confusion for web administrators.</li>
<li>Apache must be compiled with <module>mod_auth</module> in order to
use FrontPage support. This is because Apache will still use
the <module>mod_auth</module> group file for determine the extent of a
user's access to the FrontPage web.</li>
<li>The directives must be put in the <code>.htaccess</code>
files. Attempting to put them inside <directive module="core"
type="section">Location</directive> or <directive module="core"
type="section">Directory</directive> directives won't work. This
is because <module>mod_auth_ldap</module> has to be able to grab
the <directive module="mod_auth">AuthUserFile</directive>
directive that is found in FrontPage <code>.htaccess</code>
files so that it knows where to look for the valid user list. If
the <module>mod_auth_ldap</module> directives aren't in the same
<code>.htaccess</code> file as the FrontPage directives, then
the hack won't work, because <module>mod_auth_ldap</module> will
never get a chance to process the <code>.htaccess</code> file,
and won't be able to find the FrontPage-managed user file.</li>

<p>An RFC 2255 URL which specifies the LDAP search parameters
to use. The syntax of the URL is</p>
<example>ldap://host:port/basedn?attribute?scope?filter</example>
<dl>
<dt>ldap</dt>
<dd>For regular ldap, use the
string <code>ldap</code>. For secure LDAP, use <code>ldaps</code>
instead. Secure LDAP is only available if Apache was linked
to an LDAP library with SSL support.</dd>
<dt>host:port</dt>
<dd>
<p>The name/port of the ldap server (defaults to
<code>localhost:389</code> for <code>ldap</code>, and
<code>localhost:636</code> for <code>ldaps</code>). To
specify multiple, redundant LDAP servers, just list all
servers, separated by spaces. <module>mod_auth_ldap</module>
will try connecting to each server in turn, until it makes a
successful connection.</p>
<p>Once a connection has been made to a server, that
connection remains active for the life of the
<code>httpd</code> process, or until the LDAP server goes
down.</p>
<p>If the LDAP server goes down and breaks an existing
connection, <module>mod_auth_ldap</module> will attempt to
re-connect, starting with the primary server, and trying
each redundant server in turn. Note that this is different
than a true round-robin search.</p>
</dd>
<dt>basedn</dt>
<dd>The DN of the branch of the
directory where all searches should start from. At the very
least, this must be the top of your directory tree, but
could also specify a subtree in the directory.</dd>
<dt>attribute</dt>
<dd>The attribute to search for.
Although RFC 2255 allows a comma-separated list of
attributes, only the first attribute will be used, no
matter how many are provided. If no attributes are
provided, the default is to use <code>uid</code>. It's a good
idea to choose an attribute that will be unique across all
entries in the subtree you will be using.</dd>
<dt>scope</dt>
<dd>The scope of the search. Can be either <code>one</code> or
<code>sub</code>. Note that a scope of <code>base</code> is
also supported by RFC 2255, but is not supported by this
module. If the scope is not provided, or if <code>base</code> scope
is specified, the default is to use a scope of
<code>sub</code>.</dd>
<dt>filter</dt>
<dd>A valid LDAP search filter. If
not provided, defaults to <code>(objectClass=*)</code>, which
will search for all objects in the tree. Filters are
limited to approximately 8000 characters (the definition of
<code>MAX_STRING_LEN</code> in the Apache source code). This
should be than sufficient for any application.</dd>
</dl>
<p>When doing searches, the attribute, filter and username passed
by the HTTP client are combined to create a search filter that
looks like
<code>(&(<em>filter</em>)(<em>attribute</em>=<em>username</em>))</code>.</p>
<p>For example, consider an URL of
<code>ldap://ldap.airius.com/o=Airius?cn?sub?(posixid=*)</code>. When
a client attempts to connect using a username of <code>Babs
Jenson</code>, the resulting search filter will be
<code>(&(posixid=*)(cn=Babs Jenson))</code>.</p>

module="mod_auth_ldap">AuthLDAPURL</directive> URLs.</p>

<h2><a name="operation">Operation</a></h2>
<p>There are two phases in granting access to a user. The first
phase is authentication, in which <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code>
verifies that the user's credentials are valid. This also called
the <em>search/bind</em> phase. The second phase is
authorization, in which <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> determines
if the authenticated user is allowed access to the resource in
question. This is also known as the <em>compare</em>
phase.</p>
<h3><a name="authenphase">The Authentication
Phase</a></h3>
<p>During the authentication phase, <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code>
searches for an entry in the directory that matches the username
that the HTTP client passes. If a single unique match is found,
then <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> attempts to bind to the
directory server using the DN of the entry plus the password
provided by the HTTP client. Because it does a search, then a
bind, it is often referred to as the search/bind phase. Here are
the steps taken during the search/bind phase.</p>
<ol>
<li>Generate a search filter by combining the attribute and
filter provided in the <a href="#authldapurl" class="directive"><code class="directive">AuthLDAPURL</code></a> directive with
the username passed by the HTTP client.</li>
<li>Search the directory using the generated filter. If the
search does not return exactly one entry, deny or decline
access.</li>
<li>Fetch the distinguished name of the entry retrieved from
the search and attempt to bind to the LDAP server using the
DN and the password passed by the HTTP client. If the bind is
unsuccessful, deny or decline access.</li>
</ol>
<p>The following directives are used during the search/bind
phase</p>
<table>
<tr>
<td><a href="#authldapurl" class="directive"><code class="directive">AuthLDAPURL</code></a></td>
<td>Specifies the LDAP server, the
base DN, the attribute to use in the search, as well as the
extra search filter to use.</td>
</tr>
<tr>
<td><a href="#authldapbinddn" class="directive"><code class="directive">AuthLDAPBindDN</code></a></td>
<td>An optional DN to bind with
during the search phase.</td>

<h3><a name="authorphase">The Authorization
Phase</a></h3>
<p>During the authorization phase, <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code>
attempts to determine if the user is authorized to access the
resource. Many of these checks require
<code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> to do a compare operation on the
LDAP server. This is why this phase is often referred to as the
compare phase. <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> accepts the
following <a href="../mod/core.html#require" class="directive"><code class="directive">Require</code></a>
directives to determine if the credentials are acceptable:</p>
<ul>
<li>Grant access if there is a <a href="#requser"><code>require
valid-user</code></a> directive.</li>
<li>Grant access if there is a <a href="#reqgroup"><code>require user</code></a> directive, and the
username in the directive matches the username passed by the
client.</li>
<li>Grant access if there is a <a href="#reqdn"><code>require
dn</code></a> directive, and the DN in the directive matches
the DN fetched from the LDAP directory.</li>
<li>Grant access if there is a <a href="#reqgroup"><code>require group</code></a> directive, and
the DN fetched from the LDAP directory (or the username
passed by the client) occurs in the LDAP group.</li>
<li>otherwise, deny or decline access</li>
</ul>
<p><code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> uses the following directives during the
compare phase:</p>
<table>
<tr>
<td><a href="#authldapurl" class="directive"><code class="directive">AuthLDAPURL</code></a> </td>
<td>The attribute specified in the
URL is used in compare operations for the <code>require
user</code> operation.</td>

</tr>
</table>
<h2><a name="requiredirectives">The require Directives</a></h2>
<p>Apache's <a href="../mod/core.html#require" class="directive"><code class="directive">Require</code></a>
directives are used during the authorization phase to ensure that
a user is allowed to access a resource.</p>
<h3><a name="reqvaliduser">require
valid-user</a></h3>
<p>If this directive exists, <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> grants
access to any user that has successfully authenticated during the
search/bind phase.</p>
<h3><a name="requser">require user</a></h3>
<p>The <code>require user</code> directive specifies what
usernames can access the resource. Once
<code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> has retrieved a unique DN from the
directory, it does an LDAP compare operation using the username
specified in the <code>require user</code> to see if that username
is part of the just-fetched LDAP entry. Multiple users can be
granted access by putting multiple usernames on the line,
separated with spaces. If a username has a space in it, then it
must be the only user on the line. In this case, multiple users
can be granted access by using multiple <code>require user</code>
directives, with one user per line. For example, with a <a href="#authldapurl" class="directive"><code class="directive">AuthLDAPURL</code></a> of
<code>ldap://ldap/o=Airius?cn</code> (i.e., <code>cn</code> is
used for searches), the following require directives could be used
to restrict access:</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
require user Barbara Jenson<br>
require user Fred User<br>
require user Joe Manager<br>
</code></td></tr></table></blockquote>
<p>Because of the way that <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> handles this
directive, Barbara Jenson could sign on as <em>Barbara
Jenson</em>, <em>Babs Jenson</em> or any other <code>cn</code> that
she has in her LDAP entry. Only the single <code>require
user</code> line is needed to support all values of the attribute
in the user's entry.</p>
<p>If the <code>uid</code> attribute was used instead of the
<code>cn</code> attribute in the URL above, the above three lines
could be condensed to</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>require user bjenson fuser jmanager</code></td></tr></table></blockquote>
<h3><a name="reqgroup">require group</a></h3>
<p>This directive specifies an LDAP group whose members are
allowed access. It takes the distinguished name of the LDAP
group. For example, assume that the following entry existed in
the LDAP directory:</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
dn: cn=Administrators, o=Airius<br>
objectClass: groupOfUniqueNames<br>
uniqueMember: cn=Barbara Jenson, o=Airius<br>
uniqueMember: cn=Fred User, o=Airius<br>
</code></td></tr></table></blockquote>
<p>The following directive would grant access to both Fred and
Barbara:</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>require group cn=Administrators, o=Airius</code></td></tr></table></blockquote>
<p>Behavior of this directive is modified by the <a href="#authldapgroupattribute" class="directive"><code class="directive">AuthLDAPGroupAttribute</code></a> and
<a href="#authldapgroupattributeisdn" class="directive"><code class="directive">AuthLDAPGroupAttributeIsDN</code></a>
directives.</p>
<h3><a name="reqdn">require dn</a></h3>
<p>The <code>require dn</code> directive allows the administrator
to grant access based on distinguished names. It specifies a DN
that must match for access to be granted. If the distinguished
name that was retrieved from the directory server matches the
distinguished name in the <code>require dn</code>, then
authorization is granted.</p>
<p>The following directive would grant access to a specific
DN:</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>require dn cn=Barbara Jenson, o=Airius</code></td></tr></table></blockquote>
<p>Behavior of this directive is modified by the <a href="#authldapcomparednonserver" class="directive"><code class="directive">AuthLDAPCompareDNOnServer</code></a>
directive.</p>
<h2><a name="examples">Examples</a></h2>
<ul>
<li>
Grant access to anyone who exists in the LDAP directory,
using their UID for searches.
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
AuthLDAPURL ldap://ldap1.airius.com:389/ou=People, o=Airius?uid?sub?(objectClass=*)<br>
require valid-user
</code></td></tr></table></blockquote>
</li>
<li>
The next example is the same as above; but with the fields
that have useful defaults omitted. Also, note the use of a
redundant LDAP server.
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>AuthLDAPURL ldap://ldap1.airius.com ldap2.airius.com/ou=People, o=Airius<br>
require valid-user
</code></td></tr></table></blockquote>
</li>
<li>
The next example is similar to the previous one, but is
uses the common name instead of the UID. Note that this
could be problematical if multiple people in the directory
share the same <code>cn</code>, because a search on <code>cn</code>
<strong>must</strong> return exactly one entry. That's why
this approach is not recommended: it's a better idea to
choose an attribute that is guaranteed unique in your
directory, such as <code>uid</code>.
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
AuthLDAPURL ldap://ldap.airius.com/ou=People, o=Airius?cn<br>
require valid-user
</code></td></tr></table></blockquote>
</li>
<li>
Grant access to anybody in the Administrators group. The
users must authenticate using their UID.
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid<br>
require group cn=Administrators, o=Airius
</code></td></tr></table></blockquote>
</li>
<li>
The next example assumes that everyone at Airius who
carries an alphanumeric pager will have an LDAP attribute
of <code>qpagePagerID</code>. The example will grant access
only to people (authenticated via their UID) who have
alphanumeric pagers:
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid??(qpagePagerID=*)<br>
require valid-user
</code></td></tr></table></blockquote>
</li>
<li>
<p>The next example demonstrates the power of using filters
to accomplish complicated administrative requirements.
Without filters, it would have been necessary to create a
new LDAP group and ensure that the group's members remain
synchronized with the pager users. This becomes trivial
with filters. The goal is to grant access to anyone who has
a filter, plus grant access to Joe Manager, who doesn't
have a pager, but does need to access the same
resource:</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>
AuthLDAPURL ldap://ldap.airius.com/o=Airius?uid??(|(qpagePagerID=*)(uid=jmanager))<br>
require valid-user
</code></td></tr></table></blockquote>
<p>This last may look confusing at first, so it helps to
evaluate what the search filter will look like based on who
connects, as shown below. The text in blue is the part that
is filled in using the attribute specified in the URL. The
text in red is the part that is filled in using the filter
specified in the URL. The text in green is filled in using
the information that is retrieved from the HTTP client. If
Fred User connects as <code>fuser</code>, the filter would look
like</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>(&<font color="red">(|(qpagePagerID=*)(uid=jmanager))</font>(<font color="blue">uid</font>=<font color="green">fuser</font>))</code></td></tr></table></blockquote>
<p>The above search will only succeed if <em>fuser</em> has a
pager. When Joe Manager connects as <em>jmanager</em>, the
filter looks like</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>(&<font color="red">(|(qpagePagerID=*)(uid=jmanager))</font>(<font color="blue">uid</font>=<font color="green">jmanager</font>))</code></td></tr></table></blockquote>
<p>The above search will succeed whether <em>jmanager</em>
has a pager or not.</p>
</li>
</ul>
<h2><a name="usingtls">Using TLS</a></h2>
<p>To use TLS, simply set the <a href="#authldapstarttls" class="directive"><code class="directive">AuthLDAPStartTLS</code></a> to on.
Nothing else needs to be done (other than ensure that your LDAP
server is configured for TLS).</p>
<h2><a name="usingssl">Using SSL</a></h2>
<p>If <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> is linked against the
Netscape/iPlanet LDAP SDK, it will not talk to any SSL server
unless that server has a certificate signed by a known Certificate
Authority. As part of the configuration
<code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> needs to be told where it can find
a database containing the known CAs. This database is in the same
format as Netscape Communicator's <code>cert7.db</code>
database. The easiest way to get this file is to start up a fresh
copy of Netscape, and grab the resulting
<code>$HOME/.netscape/cert7.db</code> file.</p>
<p>To specify a secure LDAP server, use <em>ldaps://</em> in the
<a href="#authldapurl" class="directive"><code class="directive">AuthLDAPURL</code></a>
directive, instead of <em>ldap://</em>.</p>
<h2><a name="frontpage">Using Microsoft
FrontPage with mod_auth_ldap</a></h2>
<p>Normally, FrontPage uses FrontPage-web-specific user/group
files (i.e., the <code><a href="../mod/mod_auth.html">mod_auth</a></code> module) to handle all
authentication. Unfortunately, it is not possible to just
change to LDAP authentication by adding the proper directives,
because it will break the <em>Permissions</em> forms in
the FrontPage client, which attempt to modify the standard
text-based authorization files.</p>
<p>Once a FrontPage web has been created, adding LDAP
authentication to it is a matter of adding the following
directives to <em>every</em> <code>.htaccess</code> file
that gets created in the web</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code><pre>
AuthLDAPURL the url
AuthLDAPAuthoritative off
AuthLDAPFrontPageHack on
</pre></code></td></tr></table></blockquote>
<p><a href="#authldapauthoritative" class="directive"><code class="directive">AuthLDAPAuthoritative</code></a> must be
off to allow <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> to decline group
authentication so that Apache will fall back to file
authentication for checking group membership. This allows the
FrontPage-managed group file to be used.</p>
<h3><a name="howitworks">How It Works</a></h3>
<p>FrontPage restricts access to a web by adding the <code>require
valid-user</code> directive to the <code>.htaccess</code>
files. If <a href="#authldapfrontpagehack" class="directive"><code class="directive">AuthLDAPFrontPageHack</code></a> is not
on, the <code>require valid-user</code> directive will succeed for
any user who is valid <em>as far as LDAP is
concerned</em>. This means that anybody who has an entry in
the LDAP directory is considered a valid user, whereas FrontPage
considers only those people in the local user file to be
valid. The purpose of the hack is to force Apache to consult the
local user file (which is managed by FrontPage) - instead of LDAP
- when handling the <code>require valid-user</code> directive.</p>
<p>Once directives have been added as specified above,
FrontPage users will be able to perform all management
operations from the FrontPage client.</p>
<h3><a name="fpcaveats">Caveats</a></h3>
<ul>
<li>When choosing the LDAP URL, the attribute to use for
authentication should be something that will also be valid
for putting into a <code><a href="../mod/mod_auth.html">mod_auth</a></code> user file. The user ID is
ideal for this.</li>
<li>When adding users via FrontPage, FrontPage administrators
should choose usernames that already exist in the LDAP
directory (for obvious reasons). Also, the password that the
administrator enters into the form is ignored, since Apache
will actually be authenticating against the password in the
LDAP database, and not against the password in the local user
file. This could cause confusion for web administrators.</li>
<li>Apache must be compiled with <code><a href="../mod/mod_auth.html">mod_auth</a></code> in order to
use FrontPage support. This is because Apache will still use
the <code><a href="../mod/mod_auth.html">mod_auth</a></code> group file for determine the extent of a
user's access to the FrontPage web.</li>
<li>The directives must be put in the <code>.htaccess</code>
files. Attempting to put them inside <a href="../mod/core.html#location" class="directive"><code class="directive"><Location></code></a> or <a href="../mod/core.html#directory" class="directive"><code class="directive"><Directory></code></a> directives won't work. This
is because <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> has to be able to grab
the <a href="../mod/mod_auth.html#authuserfile" class="directive"><code class="directive">AuthUserFile</code></a>
directive that is found in FrontPage <code>.htaccess</code>
files so that it knows where to look for the valid user list. If
the <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> directives aren't in the same
<code>.htaccess</code> file as the FrontPage directives, then
the hack won't work, because <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> will
never get a chance to process the <code>.htaccess</code> file,
and won't be able to find the FrontPage-managed user file.</li>

distinguished name of the client username when checking for group
membership. Otherwise, the username will be used. For example,
assume that the client sent the username <code>bjenson</code>,
which corresponds to the LDAP DN <code>cn=Babs Jenson,
o=Airius</code>. If this directive is set,
<code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> will check if the group has

<p>An RFC 2255 URL which specifies the LDAP search parameters
to use. The syntax of the URL is</p>
<blockquote><table cellpadding="10"><tr><td bgcolor="#eeeeee"><code>ldap://host:port/basedn?attribute?scope?filter</code></td></tr></table></blockquote>
<dl>
<dt>ldap</dt>
<dd>For regular ldap, use the
string <code>ldap</code>. For secure LDAP, use <code>ldaps</code>
instead. Secure LDAP is only available if Apache was linked
to an LDAP library with SSL support.</dd>
<dt>host:port</dt>
<dd>
<p>The name/port of the ldap server (defaults to
<code>localhost:389</code> for <code>ldap</code>, and
<code>localhost:636</code> for <code>ldaps</code>). To
specify multiple, redundant LDAP servers, just list all
servers, separated by spaces. <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code>
will try connecting to each server in turn, until it makes a
successful connection.</p>
<p>Once a connection has been made to a server, that
connection remains active for the life of the
<code>httpd</code> process, or until the LDAP server goes
down.</p>
<p>If the LDAP server goes down and breaks an existing
connection, <code><a href="../mod/mod_auth_ldap.html">mod_auth_ldap</a></code> will attempt to
re-connect, starting with the primary server, and trying
each redundant server in turn. Note that this is different
than a true round-robin search.</p>
</dd>
<dt>basedn</dt>
<dd>The DN of the branch of the
directory where all searches should start from. At the very
least, this must be the top of your directory tree, but
could also specify a subtree in the directory.</dd>
<dt>attribute</dt>
<dd>The attribute to search for.
Although RFC 2255 allows a comma-separated list of
attributes, only the first attribute will be used, no
matter how many are provided. If no attributes are
provided, the default is to use <code>uid</code>. It's a good
idea to choose an attribute that will be unique across all
entries in the subtree you will be using.</dd>
<dt>scope</dt>
<dd>The scope of the search. Can be either <code>one</code> or
<code>sub</code>. Note that a scope of <code>base</code> is
also supported by RFC 2255, but is not supported by this
module. If the scope is not provided, or if <code>base</code> scope
is specified, the default is to use a scope of
<code>sub</code>.</dd>
<dt>filter</dt>
<dd>A valid LDAP search filter. If
not provided, defaults to <code>(objectClass=*)</code>, which
will search for all objects in the tree. Filters are
limited to approximately 8000 characters (the definition of
<code>MAX_STRING_LEN</code> in the Apache source code). This
should be than sufficient for any application.</dd>
</dl>
<p>When doing searches, the attribute, filter and username passed
by the HTTP client are combined to create a search filter that
looks like
<code>(&(<em>filter</em>)(<em>attribute</em>=<em>username</em>))</code>.</p>
<p>For example, consider an URL of
<code>ldap://ldap.airius.com/o=Airius?cn?sub?(posixid=*)</code>. When
a client attempts to connect using a username of <code>Babs
Jenson</code>, the resulting search filter will be
<code>(&(posixid=*)(cn=Babs Jenson))</code>.</p>
