Certainly there is the LDUP working group, and they have a number of
Internet-Drafts out (but no RFCs AFAIK).  But AFAIK, none of it is
required to be implemented (please don't think I'm beating on the
LDAP guys, because they're certainly ahead of Kerberos in this
regard).

I'm not sure I can see a whole lot of value in being interoperable with
other vendors Kerberos servers; the database format tends to be very
server implementation-specific.  That's not a problem with LDAP, of
course :-)
