Re: mod_authz_svn: Failed Authorization During COPY, RENAME, MOVE (due to extra copy?)

From: Brian Brophy <brianbrophy_at_email.com>

I tried the suggested (not use LimitExcept but instead use Require
valid-user and satisfy any) but I am experiencing the same issue. The
svn copy command fails in the same way as before: first I see an
authorized copy with source = source and destination = destination
immediately followed (without any client secondary command or anything)
by a second copy of source = destination and destination = destination
where the user is '(null)' and authorization is denied, causing the full
attempted copy transaction to fail (not authorized).

Does any one have something similar to the following working?
- mod_davn_svn and mod_authz_svn
- SVN 1.3.2 (though also failed on 1.3.1 and 1.2.1)
- User authenticated by Apache mod_authz_ldap (configured to strip full
DN ... ie user uid=joesmith,ou=org,o=company gets identified in Apache
as user joesmith)
- Within mod_authz_svn, using groups to allow people like joesmith rw
perm to some sub directory (* = r is perm at / root)

I would think this would be a rather popular configuration with
companies using LDAP for authentication and that someone would have
encountered this.
