49 result == NSS_STATUS_UNAVAIL: winbind not around
50 result == NSS_STATUS_NOTFOUND: winbind around, but domain missing
51
52 Due to a bad API NSS_STATUS_NOTFOUND is returned both when winbind_off
53 and when winbind return WINBINDD_ERROR. So the semantics of this
54 routine depends on winbind_on. Grepping for winbind_off I just
55 found 3 places where winbind is turned off, and this does not conflict
56 (as far as I have seen) with the callers of is_trusted_domains.
