We went with SASL in work for two reasons:
1. it includes caching, and is therefore faster
2. it does not require a read-only account to provide authentication.
(assuming you want to manage authorization from within
apache/subversion... all you need is authentication)
If you are looking for a how to:
Google is your friend: Stephen's Java Adventures How To Apache
Subversion Active Directory
that's a blog post I wrote for setting up authentication against
active directory using sasl, apache and subversion
