Hello, I found duplicity in passdb.tdb. I deleted duplicity user (it is machine): #pdbedit -x -u FS4$ #pdbedit -Lv | grep fs4 I add new machine account with same SID: #pdbedit -a -m -u FS4 -M S-1-5-21-1022826735-1298021733-666385194-2282 #pdbedit -Lv | grep fs4 Unix username: fs4$ Logon Script: fs4_.bat Unix username: fs4$ Logon Script: fs4_.bat ...and user FS4 is twice again. Why has user FS4 in database duplicity record? It is bug tdbsam? Could I repair tdb database? If I add completly new user problem is not. I tried restart smb service, without success. Thank you for your help, Honza
