Winbind will *have* to do this unless we don't want user home directories.
However, getting returned a password entry like:
would probably be less than useful :-).
Winbind would have to be responsible for returning a reasonable shell and
home directory (it could go so far as to automount the listed directory).

Actually, I think I like Nico's latest approach:
int sid2posix(SID sid, SIDtype_t type, posix_id_t posix_id);
enum the valid SID types, and you have a call that both identifies the
type of SID and does the translation...
