      <p>Setting the <code class="directive">AuthDBMAuthoritative</code>
      directive explicitly to <strong>'off'</strong> allows for both
      authentication and authorization to be passed on to lower level
      modules (as defined in the <code>Configuration</code> and
      <code>modules.c</code> file if there is <strong>no userID</strong>
      or <strong>rule</strong> matching the supplied userID. If there is
      a userID and/or rule specified; the usual password and access
      checks will be applied and a failure will give an Authorization
      Required reply.</p>
  
      <p>So if a userID appears in the database of more than one module;
      or if a valid <code class="directive"><a href="../mod/core.html#require">Require</a></code>
      directive applies to more than one module; then the first module
      will verify the credentials; and no access is passed on;
      regardless of the <code class="directive">AuthAuthoritative</code> setting.</p>
  
      <p>A common use for this is in conjunction with one of the
      auth providers; such as <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code>. Whereas this
      DBM module supplies the bulk of the user credential checking; a
      few (administrator) related accesses fall through to a lower
      level with a well protected .htpasswd file.</p>
  
      <p>By default, control is not passed on and an unknown userID
      or rule will result in an Authorization Required reply. Not
      setting it thus keeps the system secure and forces an NCSA
      compliant behaviour.</p>
  
      <p>Security: Do consider the implications of allowing a user to
      allow fall-through in his .htaccess file; and verify that this
      is really what you want; Generally it is easier to just secure
      a single .htpasswd file, than it is to secure a database which
      might have more access interfaces.</p>

      <p>The <code class="directive">AuthDBMUserFile</code> directive sets the
      name of a DBM file containing the list of users and passwords for
      user authentication. <em>File-path</em> is the absolute path to
      the user file.</p>
  
      <p>The user file is keyed on the username. The value for a user is
      the <code>crypt()</code> encrypted password, optionally followed
      by a colon and arbitrary data. The colon and the data following it
      will be ignored by the server.</p>
  
      <p>Security: make sure that the
      <code class="directive">AuthDBMUserFile</code> is stored outside the
      document tree of the web-server; do <em>not</em> put it in the
      directory that it protects. Otherwise, clients will be able to
      download the <code class="directive">AuthDBMUserFile</code>.</p>
  
      <p>Important compatibility note: The implementation of
      "dbmopen" in the apache modules reads the string length of the
      hashed values from the DBM data structures, rather than relying
      upon the string being NULL-appended. Some applications, such as
      the Netscape web server, rely upon the string being
      NULL-appended, so if you are having trouble using DBM files
      interchangeably between applications this may be a part of the
      problem.</p>
  
      <p>A perl script called
      <a href="../programs/dbmmanage.html">dbmmanage</a> is included with

      <p>This module provides authentication front-ends such as

  <usage>
      <p>The <directive>AuthDBMUserFile</directive> directive sets the
      name of a DBM file containing the list of users and passwords for
      user authentication. <em>File-path</em> is the absolute path to
      the user file.</p>
  
      <p>The user file is keyed on the username. The value for a user is
      the <code>crypt()</code> encrypted password, optionally followed
      by a colon and arbitrary data. The colon and the data following it
      will be ignored by the server.</p>
  
      <p>Security: make sure that the
      <directive>AuthDBMUserFile</directive> is stored outside the
      document tree of the web-server; do <em>not</em> put it in the
      directory that it protects. Otherwise, clients will be able to
      download the <directive>AuthDBMUserFile</directive>.</p>
  
      <p>Important compatibility note: The implementation of
      "dbmopen" in the apache modules reads the string length of the
      hashed values from the DBM data structures, rather than relying
      upon the string being NULL-appended. Some applications, such as
      the Netscape web server, rely upon the string being
      NULL-appended, so if you are having trouble using DBM files
      interchangeably between applications this may be a part of the
      problem.</p>

  <contextlist><context>directory</context><context>.htaccess</context>

  <override>AuthConfig</override>
  
  <usage>
  
      <p>Setting the <directive>AuthDBMAuthoritative</directive>
      directive explicitly to <strong>'off'</strong> allows for both
      authentication and authorization to be passed on to lower level
      modules (as defined in the <code>Configuration</code> and
      <code>modules.c</code> file if there is <strong>no userID</strong>
      or <strong>rule</strong> matching the supplied userID. If there is
      a userID and/or rule specified; the usual password and access
      checks will be applied and a failure will give an Authorization
      Required reply.</p>
  
      <p>So if a userID appears in the database of more than one module;
      or if a valid <directive module="core">Require</directive>
      directive applies to more than one module; then the first module
      will verify the credentials; and no access is passed on;
      regardless of the <directive>AuthAuthoritative</directive> setting.</p>
  
      <p>A common use for this is in conjunction with one of the
      auth providers; such as <module>mod_authn_file</module>. Whereas this
      DBM module supplies the bulk of the user credential checking; a
      few (administrator) related accesses fall through to a lower
      level with a well protected .htpasswd file.</p>
  
      <p>By default, control is not passed on and an unknown userID
      or rule will result in an Authorization Required reply. Not
      setting it thus keeps the system secure and forces an NCSA
      compliant behaviour.</p>
  
      <p>Security: Do consider the implications of allowing a user to
      allow fall-through in his .htaccess file; and verify that this
      is really what you want; Generally it is easier to just secure
      a single .htpasswd file, than it is to secure a database which
      might have more access interfaces.</p>

      <p>The <code class="directive">AuthUserFile</code> directive sets the name
      of a textual file containing the list of users and passwords for

      <p>The <code class="directive">AuthDBMGroupFile</code> directive sets the
      name of a DBM file containing the list of user groups for user
      authentication.  <em>File-path</em> is the absolute path to the
      group file.</p>
  
      <p>The group file is keyed on the username. The value for a
      user is a comma-separated list of the groups to which the users
      belongs. There must be no whitespace within the value, and it
      must never contain any colons.</p>
  
      <p>Security: make sure that the
      <code class="directive">AuthDBMGroupFile</code> is stored outside the
      document tree of the web-server; do <em>not</em> put it in the
      directory that it protects. Otherwise, clients will be able to
      download the <code class="directive">AuthDBMGroupFile</code> unless
      otherwise protected.</p>
  
      <p>Combining Group and Password DBM files: In some cases it is
      easier to manage a single database which contains both the
      password and group details for each user. This simplifies any
      support programs that need to be written: they now only have to
      deal with writing to and locking a single DBM file. This can be
      accomplished by first setting the group and password files to
      point to the same DBM:</p>
  
  <div class="example"><p><code>
  AuthDBMGroupFile /www/userbase<br />
  AuthDBMUserFile /www/userbase
  </code></p></div>
  
      <p>The key for the single DBM is the username. The value consists
      of</p>
  
  <div class="example"><p><code>Unix Crypt-ed Password : List of Groups [ : (ignored)
        ]</code></p></div>
  
      <p>The password section contains the Unix <code>crypt()</code>
      password as before. This is followed by a colon and the comma
      separated list of groups. Other data may optionally be left in the
      DBM file after another colon; it is ignored by the authentication
      module. This is what www.telescope.org uses for its combined
      password and group database.</p>

      <p>Setting the <code class="directive">AuthzDBMAuthoritative</code>
      directive explicitly to <strong>'off'</strong> allows for both
      authentication and authorization to be passed on to lower level
      modules (as defined in the <code>Configuration</code> and
      <code>modules.c</code> file if there is <strong>no userID</strong>
      or <strong>rule</strong> matching the supplied userID. If there is
      a userID and/or rule specified; the usual password and access
      checks will be applied and a failure will give an Authorization
      Required reply.</p>
  
      <p>So if a userID appears in the database of more than one module;
      or if a valid <code class="directive"><a href="../mod/core.html#require">Require</a></code>
      directive applies to more than one module; then the first module
      will verify the credentials; and no access is passed on;
      regardless of the <code class="directive">AuthAuthoritative</code> setting.</p>
  
      <p>A common use for this is in conjunction with one of the
      auth providers; such as <code class="module"><a href="../mod/mod_authn_file.html">mod_authn_file</a></code>. Whereas this
      DBM module supplies the bulk of the user credential checking; a
      few (administrator) related accesses fall through to a lower
      level with a well protected .htpasswd file.</p>
  
      <p>By default, control is not passed on and an unknown userID
      or rule will result in an Authorization Required reply. Not
      setting it thus keeps the system secure and forces an NCSA
      compliant behaviour.</p>
  
      <p>Security: Do consider the implications of allowing a user to
      allow fall-through in his .htaccess file; and verify that this
      is really what you want; Generally it is easier to just secure
      a single .htpasswd file, than it is to secure a database which
      might have more access interfaces.</p>

      <p>Setting the <code class="directive">AuthzGroupFileAuthoritative</code>
      directive explicitly to <strong>'off'</strong> allows for
      authorization to be passed on to lower level modules (as defined in
      the <code>Configuration</code> and <code>modules.c</code> file if
      there is <strong>no userID</strong> or <strong>rule</strong> matching
      the supplied userID. If there is a userID and/or rule specified; the
      usual password and access checks will be applied and a failure will
      give an Authorization Required reply.</p>
  
      <p>So if a valid <code class="directive"><a href="../mod/core.html#require">Require</a></code>
      directive applies to more than one module; then the first module

      regardless of the <code class="directive">AuthzGroupFileAuthoritative</code>
      setting.</p>
  
      <p>By default, control is not passed on and an unknown userID
      or rule will result in an Authorization Required reply. Not
      setting it thus keeps the system secure and forces an NCSA
      compliant behaviour.</p>
  
      <p>Security: Do consider the implications of allowing a user to
      allow fall-through in his .htaccess file; and verify that this
      is really what you want; Generally it is easier to just secure
      a single .htpasswd file, than it is to secure a database which
      might have more access interfaces.</p>

  <usage>
      <p>The <directive>AuthGroupFile</directive> directive sets the
      name of a textual file containing the list of user groups for user
      authentication.  <em>File-path</em> is the path to the group
      file. If it is not absolute (<em>i.e.</em>, if it doesn't begin
      with a slash), it is treated as relative to the <directive
      module="core">ServerRoot</directive>.</p>
  
      <p>Each line of the group file contains a groupname followed by a
      colon, followed by the member usernames separated by spaces.
      Example:</p> 
  
      <example>mygroup: bob joe anne</example> 
  
      <p>Note that searching large text files is <em>very</em>
      inefficient; <directive
      module="mod_authz_dbm">AuthDBMGroupFile</directive> should be used
