RE: AuthzSVNAccessFile and branching

Eric,

I'm out of the useful things to test, maybe someone else on this list
can help? This should be and probably is a trivial thing, but I don't
see it.
I'm still not sure about the (null) part in the error logs, it doesn't
seem to be right.

In such a situation, I'd try to find the root cause of the problem by
trying other setups.

Maybe you can:

1) see if it is the repository
- make a new empty repository, and add trunk & branches folders
- add this new repository in you svn-access-file like:
  [newrepo:/]
  @developers = rw
- do an svn copy http://xyz.com/repos/newrepo/trunk
http://xyz.com/repos/newrepo/branches/1 -m "test branch"

2) check the ldap part
- make a new location in your apache config file, but without ldap
<Location /svn>
   DAV svn
   SVNPath /svn/newrepo
   AuthzSVNAccessFile /svn/svn-newrepo-access-file
   AuthType Basic
   AuthName "Subversion repository"
   AuthUserFile /svn/svn-newrepo-auth-file
   Require valid-user
</Location>
- make a new svn-access-file with only this:
[groups]
developers = user1

[newrepo:/]
@developers = rw
- you have to create a user in the /etc/svn-auth-file also
>htpasswd -c /svn/svn-newrepo-auth-file user1 password

3) btw, what's the version of your svn client?
        what's the version of your mod_dav_svn?

4) try to install SVN on another machine,
   try putting the repositories in another folder
   check that the apache user has full rights on the svn folder
   try running svnserve instead of apache
   ...
   ( I know these don't seem to be relevant, you never know )

Hope some of this helps before your forehead explodes :))

Lieven.

Thanks Lieven!

I am definitely at a loss here. I don't know what I am missing. A flat
spot is forming on my forehead from beating it against my desk!

  No, I didn't do this manually. It appears that the username is being
'dropped' during the COPY command. For example, when I issue the svn copy
command, here is the access_log entries:

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

There error_log contains the same a posted before:

[Thu Jul 07 11:25:28 2005] [error] [client 10.31.1.21] Access denied:
'(null)' COPY landfill:/branches/3.0 landfill:/branches/3.0 [Thu Jul 07
11:25:28 2005] [error] [client 10.31.1.21] Access denied:
'(null)' COPY landfill:/branches/3.0 landfill:/branches/3.0 [Thu Jul 07
11:25:28 2005] [error] [client 10.31.1.21] Access denied:
'(null)' COPY landfill:/branches/3.0 landfill:/branches/3.0

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

From the access_log, it appears that it has the username (user1) during the
COPY, but it receives the 401 response and then I get the entries in the
error_log indicating the 'null' for username. Is it getting dropped
somewhere??

  attempted to create several unique branches -- same result for all

These entries were part of a sample config I found (I had to teach myself
Linux in order to implement Subversion -- Linux was required by my boss --
anyway, I am not sure about those entries) I commented them out and still
received the same results

I performed the upgrade to 1.2.1 and still receive the same results. The
access and error_logs in response #1 are from 1.2.1

Tried specifying the username and password and no change. I am pretty
confident that it is picking up the username correctly as it is reflected in

the access_logs.
