Description

This is the upstream copy of https://bugzilla.redhat.com/show_bug.cgi?id=656906

Especially for the Kerberos provider it would be useful to allow a protocol fallback for DNS SRV queries. We should query _udp first and then _tcp if no _udp record was found.

But I think we should use this only for the lookups and not restrict the Kerberos library to the found protocol. Because libkrb5 will do to fallback from udp to tcp automatically if the udp connection fails.
