I take a look, can you reproduce this at will?
If so, can you please provide a log level = 10 logfile (log.wb-DPTINFO and log.winbindd). While creating them, please set "max log size = 0".
yes I can reproduce it everytime. But now, I'm unable to attach a file in the bugzilla (connection reset?), so I've made the two logs files online with loglevel = 10: http://manu.agat.net/log.wb-DPTINFO http://manu.agat.net/log.winbindd
(I forgot to precise the time of the crash in the logs: 10h07 the 15/08/2007
too old version, not more able to reproduce it, so closing...
