> 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.
