Title: #214: UTIL: Set udp_preference_limit=0 in krb5 snippet
@frozencemetery: is your comment still valid for the latest version of this patch? I'm
not sure whether @celestian updated this patch after your comment or not and excuse me in
case I'm mistaken, but now seems that those patches are setting `udp_preference_limit
= 0` conditionally in the krb5 snippet.
