Re: ACL problem

Ok, i just commented in Domain.xml the default permissions for all users
in for /files

<objectnode classname="org.apache.slide.structure.SubjectNode"
uri="/files">
    <permission action="all" subject="unauthenticated" inheritable="true"/>
    <!--<permission action="/actions/write" subject="/roles/user" inheritable="true"/>-->
    <permission action="/actions/read-acl" subject="owner" inheritable="true"/>
</objectnode>


Now, everytime i create a new folder under /files i specify the proper
permissions (ie. deny all for /slide/roles/user and grant all to the
"owner" /slide/users/usernamehere, remember that the order is very
important -first match=rule applied- verify the right order with a
webdav client)

I wrote "owner" because in my case the real owner is
always /slide/users/root but the "fake" owner is which have all
permissions granted.

fyi. Im not denying "read" to everybody in /files, so this way a user
with several folders under /files can list all of them without a
problem.


Hope this helps

Carlos

If User A is in Accounting and User B is in Engineering I do not want them
to be able to see the same files but I want them both to be able to write
and have full access to files within their same roles.

Hi Kevin!

Maybe I missed something. But if you have allow all to authenticated users
-
then why should your case with user A and B not be allowed?

JNDI and OpenLDAP access

Posted by Ke...@sybase.com.
This is a question for people who have implemented the
JNDIPrincipalStrore/LDAP (openLDAP)

What do you have defined in your slapd.conf?
I am looking for some examples, I have the following but it is too
restrictive and does not allow access.

access to attr=userpassword
       by self       write
       by anonymous  auth
       by *          none

access to *
       by self       write
       by users      read
       by *          none

If I have the normal access open to all it works.

 access to *
      by * read

acl question

Posted by Ke...@sybase.com.
In my domain.xml I have setup permission such that under "/" all can
read-acl, write-acl, unlock and read (the default)
  <permission action="/actions/read-acl" subject="all" inheritable="true"
negative="true"/>
  <permission action="/actions/write-acl" subject="all" inheritable="true"
negative="true"/>
  <permission action="/actions/unlock" subject="all" inheritable="true"
negative="true"/>
  <permission action="/actions/read" subject="all" inheritable="true"/>

Under "/files" I have setup permission such that anyone authenticated can
do anything, write if authenticated (although redundant I think),

and the owner can read-acl (also redundant?)

  <permission action="all" subject="authenticated" inheritable="true"/>
  <permission action="/actions/write" subject="authenticated" inheritable=
"true"/>
  <permission action="/actions/read-acl" subject="owner" inheritable="true"
/>

I am using the JNDIPrincipalStore for user and roles so this is all I have
in the domain.xml (default from the JNDI example):

                        <objectnode classname=
"org.apache.slide.structure.SubjectNode" uri="/users">
                              <permission action="all" subject="self"
inheritable="true"/>
                              <permission action="all" subject=
"authenticated" inheritable="true" negative="true"/>
                        </objectnode>
                        <objectnode classname=
"org.apache.slide.structure.SubjectNode" uri="/roles">
                              <permission action="all" subject="self"
inheritable="true"/>
                              <permission action="all" subject=
"authenticated" inheritable="true" negative="true"/>
                        </objectnode>

User A authenticates and writes file X to the WebDAV server.

User B authenticates and changes the contents of file X on the server.

The problem is that user A and user B belong different roles and should not
be able to do this.

How or where do I define this restriction?

Thanks

WebdavResource clarification

Posted by Ke...@sybase.com.
Could someone help explain the difference (pros and cons) of getting a
WebdavResource to work with b/t the following.
Is one faster than the other, more overhead, ...?

1.    HttpURL httpUrl = new HttpURL("http://localhost:16080/slide/files");
      httpUrl.setUserinfo(JAASSecurityUtil.getUsername(), "operator");
      WebdavResource wr = new WebdavResource(httpUrl);

2.    Context ic = new InitialContext();
      WebDAVConnectionFactory _factory = (WebDAVConnectionFactory)
ic.lookup("java:comp/env/WebDAV-Connector");
      WebDAVConnectionSpec _spec = new WebDAVConnectionSpec(host,
JAASSecurityUtil.getUsername(), "", timeout);
      WebDAVConnection conn = _factory.getConnection(_spec)
      WebdavResource wr = conn.getWebdavResource();

The first one I can use in both a webapp and a java client app.
The second one I was only able to figure out how to use in a webapp.
