This has been discussed here before. The solution that we recommend is
to use
Heimdal with PADL's hdb-ldap backend and Symas' patches. (Not all of the
patches were present in Heimdal 0.5.2 so it seems you still have to
some by hand.) This approach gives the tightest integration, putting the
Kerberos user database in LDAP itself.
