Hm, I'm going to need more information in both cases to be able to track
this down. At least, the debug logging output is needed. Having a
pre-existing context without having a valid cache in that context is
something that shouldn't happen; pam_authenticate clears the context from
the PAM environment if it was unable to create a ticket cache.

Similarly, with obtaining the old authentication tokens, that code is very
straightforward and I don't know why that would fail. I need more
information on exactly what the return status for pam_get_item would be.
If you enable use_authtok instead of use_first_pass, you should get an
error message and an abort in the PAM stack if pam-krb5 can't retrieve the
authentication token.

Thank you for looking at this! I'd love to get it to work.
