Hello all. I'm trying to investigate a problem that occur every days and force me to restart samba. I'm using samba 3.5.6 (last stable) ? winbind joining windows ads. Every day, at unpredictable time, the logs show me: Jan 17 08:24:53 xxx winbindd[13585]: Kinit failed: Preauthentication failed Jan 17 08:24:53 xxx winbindd[13584]: [2011/01/17 08:24:53.550079, 0] libsmb/cliconnect.c:1052(cli_session_setup_spnego) Jan 17 08:24:53 xxx winbindd[13584]: Kinit failed: Preauthentication failed So i need to restart samba in order to let authentication restart normally. I have upgraded for 3.0.36 (this version had no problem at all). Someone can help me to solve that?
