I have created a new blog entry on the openCollabnet Subversion Blog explaining the intricacies of exposing Subversion via Apache with LDAP support. Here is the direct link: http://blogs.open.collab.net/svn/2009/03/subversion-with-apache-and-ldap-updated.html. The purpose of this new blog entry was to replace the extremely deprecated and aging entry previously posted on openCollabNet. I hope this new blog entry helps making the use of LDAP for Subversion authentication much easier.
