Samba includes the user's long-term credentials (encrypted in the AS reply key) to allow legacy authentication protocols such as NTLM to work even if the pre-authentication mechanism replaced the reply key (as PKINIT does). Samba also needs to know whether the client explicitly requested a PAC be included (or excluded), in order to defer PAC exclusion until a service ticket is issued (thereby avoiding a name binding attack if the user is renamed between TGT and service ticket issuance).
