-----------------------------------
Todd, sorry for late reply. I just got back after a long leave. And sorry for
not being able to commit it as I'm not a committer yet. :)

> In working on securing a daemon that uses two different principals from
> different threads, I found that I wasn't able to login from a second keytab
> after I'd logged in from the first. This is because we don't set the
> refreshKrb5Config in the Configuration for the Krb5LoginModule - hence it
> won't switch over to the correct keytab file if it's different than the first.
