Nested AD groups aren't supported -- not many products do. Typically, support for nested AD groups requires that the client application use the native AD APIs rather than generic LDAP APIs.

Subject: SVN group authentication to AD

Hello,

    I've been banging my head on this one for 2 days now.

I've googled this issue but it appears not many admins are using this and/or

it could possibly be a bug in the apache module.

Config

------

Red Hat Enterprise Linux Server release 5.5 (Tikanga)

Server version: Apache/2.2.3

svn, version 1.6.12 (r955767)

Windows 2008 R2

   It appears that we cannot use Active Directory Permissions Groups

with the s-svn server for Subversion repository authentication and authorization

but yet AD Role groups work just fine.

subversion.conf config for "puppet" repository

------------------------------------------------

#================puppet repo===================================

<Location /puppet>

   DAV svn

   SVNPath /repos/puppet

   AuthPAM_Enabled on

   AuthType Basic

   AuthName "Subversion Authentication to AD"

   # Limit R/W access to certain role groups

   <LimitExcept GET PROPFIND OPTIONS REPORT>

# Require group SVN-Puppet-ReadWrite-P

      Require group IT-InfrastructureTeam-SystemAdministrator-R

   </LimitExcept>

   # Limit R/O access to certain role group

   <Limit GET PROPFIND OPTIONS REPORT>

# Require group SVN-Puppet-ReadWrite-P

      Require group IT-InfrastructureTeam-SystemAdministrator-R

   </Limit>

</Location>

The interesting thing is that AD Role Groups appear to work fine within

the Location directive config above which shows the role group for which

I'm a member.

If the above config is changed to use the Permissions group shown commented

out, authentication doesn't work and when that happens I'm seeing the following

error in ssl_error_log.

[Fri Nov 12 13:10:18 2010] [error] [client 172.16.4.7] GROUP: dpb not in required group(s).

So, even though the following User > Role > Permissions > Resource association

exists, the group with '-P' in it above won't allow dpb to authenticate for repo access.

dpb is a member of IT-InfrastructureTeam-SystemAdministrator-R and

IT-InfrastructureTeam-SystemAdministrator-R is a member of SVN-Puppet-ReadWrite-P AD

group

Any help would be greatly appreciated.
