Apache/LDAP/SVn --- ldap using Read-Only/READWRITE groups for each repository?

Ok,

I am having problems configuring Apache, LDAP, and SVN into one nice piece.
What I am setting up one Parent SVN directory then attempting to perform the
control with Apache Location, and Limit directives.

My goal, at each repository level to have projects R/W and Read-Only based on
different LDAP Groups.

Here is what I have been trying without real success that I can see, can you
all suggest what I should be doing here?

I'd like to do all the protections using LDAP groups as we have a method of
selected group changes by designated administrators. Maintaining the standard
file would be much more painful for us.

HELP?

Thanks.
