apache 2.2 - mod_dav_svn not allowing authenticated users

I am running a CentOS 6.3 server along with a custom compile apache 2.4.3 (compile line below) and custom compiled subversion 1.7.8 (again, compile line below).

I have mod_dav_svn set up, and it half works. If I go to svn.domain.com/svn it asks me for my username and password. I can log in fine (it only asks me once) and I can browse through the repositories no problem. If I then go to tortoisesvn on a windows machine and try to check outa repository (svn.domain.com/svn/testrepo for example) the login window pops up. I type my credentials in and hit save and then ok. The window pops up again. I can keep typing my credentials in over and over, and it doesn't do anything (it acts like my username and password are wrong but I know they aren't). Nothing is showing up in the error log, and nothing weird is showing up in the access log.
If I disable the authentication, everything works perfectly.
Halp!

EDIT: I did a "chmod -R 777 /u01/svn" to see if that fixed the problem. No dice. The svnauth file is also 777 for the same reason.

Answer

Get rid of the DocumentRoot directive. It's not valid with DAV svn.
