+Previously, when Samba was a domain member and a client was connecting using an
+untrusted domain name, such as BOGUS\user smbd would remap the untrusted
+domain to the primary domain smbd was a member of and attempt authentication
+using that DOMAIN\user name. This differed from how a Windows member server
+would behave. Now, smbd will replace the BOGUS name with it's SAM name. In
+the case where smbd is acting as a PDC this will be DOMAIN\user. In the case
+where smbd is acting as a domain member server this will be WORKSTATION\user.
+Thus, smbd will never assume that an incoming user name which is not qualified
+with the same primary domain, is part of smbd's primary domain.
