Are they really using stock 1.3?  I'm fairly certain we fixed this bug
late in the 1.3 release cycle before the release.

It certainly does.  There is not a krb5.conf parameter to adjust this
(nor is there one documented) in the MIT code.

I don't see why not; it is a fairly strange request though.

If renewable_ok is set, yes.  That's what the spec says.
