Description

Currently Kerberos errors are presented as a stack trace to the user looking something like:

GSSError: (('Unspecified GSS failure.  Minor code may provide more information', 851968), ('No Kerberos credentials available', -1765328243))
401 Client Error: Authorization Required

(And similar for expired tickets). It would be helpful to catch these and display more useful information, such as a suggestion to run kinit.
