I think Subauthz is finally ready to be used. The feature-set is nearly completed, and I think it’s quite enough to manage Subversion’s current authentication features for one or multiple repositories.

I’m trying to get the time to write a quick tutorial on usage, though it must be quite straightforwarded. Take a look at the installation instructions
here.

You can test it in
http://subauthz.omelas.net, or you can download it from the repository.
