I'm sorry if the title isn't very precise, but that's really all there is to it.
I'm running Apache 2.2 on my computer to host a LAN subversion server. Since it's local-only, I don't need strict security, and there are no authentication directives set.
<Location /svn> DAV svn SVNPath /path/to/repos Order deny,allow Allow from 192.168.1.0/8 </Location>
This works well to the extent of saving revisions of my files. However, there's no author specified in the revisions as there's no authentication.
My roommate will collaborate with me on certain projects, and while it's not strictly necessary, it'd be great if we were able to sort out who made what. Of course, I could set up a simple authentication realm with two users (and there's a possibility that it's the simplest way), however I'm wondering if it's possible to have Apache authenticate me and my roommate, at least as far as SVN is concerned, based on our static LAN IP addresses (or whatever else could be used transparently as an identification factor) rather than on WWW authentication.
