Sun PCNetlink is a NT4.0 PDC emulator. I'm running samba-3.0.13, joined to an ADS server that has a trust with a PCNetlink domain. My samba can authenticate fine against ADS accounts, but refuses to authenticate against the PCNetlink domain. I can do getent passwd "ADSDOM\user" and get an ADS user printed out, but if I use getent passwd "NT4DOM\user" nothing prints out. However, if I use getent passwd | grep "NT4DOM\user" I see the user I'm looking for. Here's a log.winbindd with log level = 10 from when I try getent passwd "NT4DOM\user" #-- log.winbindd -- [2005/04/14 13:34:00, 10] nsswitch/winbindd.c:process_request(321) process_request: request fn GETPWNAM [2005/04/14 13:34:00, 3] nsswitch/winbindd_user.c:winbindd_getpwnam(126) [11293]: getpwnam NT4DOM\user [2005/04/14 13:34:00, 10] nsswitch/winbindd_cache.c:refresh_sequence_number(356) refresh_sequence_number: NT4DOM time ok [2005/04/14 13:34:00, 10] nsswitch/winbindd_cache.c:refresh_sequence_number(387) refresh_sequence_number: NT4DOM seq number is now 23612 [2005/04/14 13:34:00, 10] nsswitch/winbindd_cache.c:centry_expired(411) centry_expired: Key NS/NT4DOM/user for domain NT4DOM is good.
