I have, just recently in fact. The trick is to use SASL with LDAP. I only use authentication at this point and don't use AD groups for authorization.
I'm using a RHEL7 as my svn server which bundles SVN 1.7. I can't imagine the configuration of the server would be drastically different from 1.7 to 1.9.
So far the only burr in the saddle has been making sure the clients support SASL/PLAIN -- most do, but Eclipse with Subclipse was a failure.
As long as you're fine with passing credentials in cleartext, then this will work for you. If you need SSL encryption, then you will probably need to add Apache. Trying to get the RedHat-supplied svn and Apache components to work together was a non-starter, and trying to build everything from source on RHEL didn't work either.
