Re: locking down access to a repository

I've tried twice to reply to your first response. I am not sure why it is
not posting.
I am going to try again.

I have done this already. I have a separate configuration file for each
repository. That looks like this:
<Location /RepositoryName>
 dav svn
 SVNPath /disk01/home/RepositoryName
 AuthType Basic
 AuthBasicProvider ldap-FCGNET ldap-VIET
 AuthzLDAPAuthoritative off
 AuthName "CSC Subversion Repository"
 Require valid-user
 Require ldap-group CN=ADGroupName,OU=Europe,OU=Groups,DC=fcg,DC=com
 Require ldap-user pmoss

I have defined the LDAP Aliases in the very first repository configuration
file; as such:
<AuthnProviderAlias ldap ldap-FCGNET>
         AuthLDAPBindDN FCGNET\svnuser
         AuthLDAPBindPassword xxxxxxxxx
 <AuthnProviderAlias ldap ldap-VIET>
         AuthLDAPBindDN "CN=fcgvuser,OU=Service
         AuthLDAPBindPassword xxxxxxxxxxx

I think that I have 2 separate issues:
1. I need to lock down access so that only the users in the associated AD
group have access to the repository.
2. I need to be able to allow just my user account access to the
repositories, without having to be added to all of the AD groups.

Right now;
All, valid, users can access all repositories, whether they are a member
of the Active Directory group or not.
When I remove the "Require valid-user" line then no one, including the
members of the Active Directory group, can access the repository.

I think you also may need to be less specific with your ldapurl (remove
objectclass or use * ??):
(Assuming active directory, this is like what I have used in the past)

 AuthLDAPURL "ldap://
 AuthLDAPGroupAttribute member
 Require ldap-group ...

It has been quite awhile since I used ldap groups instead of authz

This first google hit has some examples:


As does this one:

Although this is probably better suited for the apache/mod_ldap list, I'll
attempt to help.

do your domain controllers support unencrypted binds (very dangerous)?
can you supply any apache/AD debug logs?
can you supply versions of apache/mod_ldap?
can you describe anything that is knows to be working?

...this should be pretty straight forward to troubleshoot if you give us
some useful information to work with.

I speak without a full understanding of the lists user base, but I bet
none of them can or ever will be able to read the minds of the end user
with a problem (let alone know how their systems are configured). If there
is such a wonderful beasty, I'd be mighty interested in meeting them.
