I wish I had a better memory, but I vaguely recall going down this path once before between
server-merge and dir-merge (mailing list archives might remember better than I do) .  I know
that when it comes to anything SSL related, not all LDAP SDKs can handle per-directory options.
 Novell LDAP SDK being one of them.  So when it comes to setting options on a per-directory
basis, it might get a little tricky depending on the LDAP SDK that is being used.
