Winbind crashed on a machine this week, and it seemed to take anything PAM related with it. Had to do a reboot. How do I read this crash dump that was written to winbindd.log, so I can make sure it doesn't happen again? <quote> [2006/08/17 15:03:14, 1] nsswitch/winbindd_group.c:winbindd_getgrnam(255) group linux_admins in domain MTL-TOUCHTUNES does not exist [2006/08/17 16:36:02, 0] libsmb/clientgen.c:cli_rpc_pipe_close(375) [2006/08/17 15:48:01, 1] nsswitch/winbindd.c:main(978) winbindd version 3.0.22-1.fc5 started.
