The SunRPC protocol (rfc1831) states clearly that the AUTH_SYS (a.k.a. AUTH_UNIX) structure is defined as struct authsys_parms { unsigned int stamp; string machinename<255>; unsigned int uid; unsigned int gid; unsigned int gids<16>; }; If the BSDs are playing around with that, then they are not adhering to the protocol, and will be incompatible with all other SunRPC implementations.
