Solaris pam_krb5 session cleanup

[Henry B. Hotz]

The pam_krb5 session module is supposed to clean up your credentials on  
logout (if you are the last logout for that session).

I had a Solaris 9 machine which did that.  Now I have a different S9  
machine which doesn't.  Any suggestions for what to look for?
