The client will send this + option if the client_aware_gss_bindings profile option is set. + +User experience: + +* The default setting of dns_canonicalize_realm is now "fallback". + Hostnames provided from applications will be tried in principal + names as given (possibly with shortname qualification), falling back + to the canonicalized name. + +* kinit will now issue a warning if the des3-cbc-sha1 encryption type + is used in the reply.
