Phase 1 of this project (which this patch aims to implement) is to handle
Kerberos logins to pgAdmin when running in server mode (as we’ve already
done for LDAP, except KRB authenticated users don’t see a login page of
course). Phase 2 will add support for logging into the PostgreSQL servers -
I believe that is where we’ll need to handle delegated credentials, correct?
