It only strips the default domain. All the others are untouched. It is
(essentially) also only in the getpwnam() and pam codepaths, not in the
SID->ID stuff, we generally avoid going via names as much as possible.
This is by design. The while idea of idmap_autorid and idmap_rid is
that we don't want to rely on any remote communication (eg name->sid
calls and reverse) to determine the mapping, as that could fail at the
