It looks like it works for me. I have a mod in session.c to call the get_afs_token
routine which replaces the k_afs calls. I see in the debug output that
it is indeed calling my routine and passing the delegated credentials to it
via the KRB5CCNAME environment. 

So this may be a problem with the way the k_afs works which may expect
the credentials in memory?

Here is a piece of the log on the client side. 


debug1: Setting KRB5CCNAME to FILE:/tmp/krb5cc_134_x26699   ## From gss-serv.c:
Environment:                                                ## From sesison.c copy_environment
