This issue has been reported twice this week:
http://svn.haxx.se/users/archive-2007-01/0756.shtml
http://svn.haxx.se/dev/archive-2007-01/0416.shtml
Description:
> Anyway, the issue is when you set up specific directory permissions as such:
>
> [groups]
> groupAB = userA,userB
>
> [/]
> * =
> @groupAB = rw
>
> [/a]
> userC = rw
>
> This means that userA and userB have full access throughout the entire
> repository, but userC only has access to the subfolder 'a'. When userC
> updates a file in this directory and commits (with or without comment) it
> succeeds. When userC locks a file in that directory, modifies it and commits
> with or without a comment it fails "Authorization failed".
The two reports both were for svnserve, it's not tested yet on apache.
