Hi, I have just loaded 2.2.3 this morning and it looks like we still have the same problem with winbindd which we had with 2.2.3pre. The winbindd log is full of : [2002/02/04 12:54:18, 0] nsswitch/winbindd_group.c:winbindd_getgrnam_from_group(220) getgrname_from_group(): could not get domain sid for domain @UK Eventually the normal function of winbind stops, despite 'wbinfo -t' reporting that the 'secret is good'. Once winbind is restarted then it returns to full function - although the above messages continue. Whilst this happened with 2.2.3pre, after a few days winbindd stopped working altogether and refused to even load. My fix for this was to fallback to the winbindd/wbinfo 2.2.2 binaries and deal with the memory leak which we have been doing successfully for the last few weeks. I'll increase the log level and see if I can pinpoint the problem but I think we are heading for another series of panics etc. If it comes to it, I'll recompile with the debug info and try and capture a backtrace (and send it to Tim ?) Cheers, Noel
