This I agree with.  At this point we're all speculating about what
directions the deployers of Kerberos will want to go.

The conversation is also rather muddled by the fact that the current
database backends are not particularly great at being solid database
backends.  They've been used extensively for years and are therefore quite
stable, but that's nearly the only positive, and there are a lot of
negatives.  I can certainly agree with a litany of complaints about db2!
But I think many of them are problems with that particular form of a
database backend, not with the idea of not using LDAP.

I think we can find substantial common ground in the last sentence.  While
at this point I'm dubious that I would ever want to use an LDAP backend, I
have no problem with treating it as a first-class citizen, and I know that
many people do indeed want to use it.
