Solaris 10 sshd + GSSAPI = where's my cred cache?

[Jeff Blaine]

I apologize for the general nature of this post.  Maybe it's
better posted to the secureshell list which is loaded with
spam and is often choked up sitting on some server somewhere,
but...

I can ssh with GSSAPI auth to a Solaris 10 box fine.  When
I'm in though, klist says I have no credential cache and
there's nothing useful in /tmp.

Has anyone come across this and found an answer?
