Thank you for your suggestions!

mod_ldap for performance improvement is a further consideration.

Actually I want to add ldap support for mod_authz_svn most.
As far as I can see, when we need ldap authentication, we would take these combination 'apache + subversioin'.
Is it a good idea to move ldap.c from libsvn_subr to mod_authz_svn ?

Further more, I will make ldap group support an optional feature when building.

As to variable names, I am considering just reuse the variable names of mod_authnz_ldap.
If we define these variable names for both mod_authnz_ldap and mod_authz_svn for the same value, I don't think it is a good idea. What do you think?
