kerberos custom credential cache

I got NFS4 with Kerberos working on a Debian server and client, but
Ive run into a problem.  Our Kerberos implementation uses a custom
credential cache, which nfs (kernel? libgssapi?) dosnt seem to
understand.  If I force the credential cache to be a file, it works
great.   Im not a great programmer, but if someone could point me in
the right direction, I am willing to attempt adding in the needed
custom changes.

Also, our site uses aes256 keys for everything, so I would like to
investigate what might be needed to support encryption types other
than single des, specifically types 16-18. Has anyone looked into
this?
