RE: Kerberos Feature Request
I want to enable that.
I'm suggesting that it would be nice if there were a MIT-independent
and KTH-independent (and CyberSafe-independent ;-) mechanism that
allowed you to do that. Given a KDC-neutral enabling mechanism I
expect that an open-source project or 10 would spontaneously form to
bridge the gap between the conformant KDCs and the LDAP server of
your choice (including true blue AD).
I'd be happy if the agreement/standard/whatever just said that you do
an ldap query for the "pac" attribute from the unique ID that matches
the principal, with the obvious REALM to DC= translation.
Jeffrey Altman objects that I want an API, not an RFC, so IETF
shouldn't be involved, but I think the example I just gave would be
an RFC. I'm trying to limit my care-about's though. I just want a
general way to make use of the feature, which is currently pretty
