Hi, I've a problem with samba and ldap but it's the first time that samba works so bad. I made a network with samba and a few of windows client. Since four months (the networks was made on january) and every 10/12 days the workstations go out from the domain. The user can't log, and when i try logging with administrator It ask me to change him password. So I must unjoin the workstation from the domain and join again. on log files i found that: auth/auth_sam.c:sam_account_ok(159) sam_account_ok: Account for user 'administrator' password expired!. [2006/10/12 18:00:18, 1] auth/auth_sam.c:sam_account_ok(160) sam_account_ok: Password expired at 'Thu, 27 Apr 2006 13:55:38 GMT' (1146138938) unix time. account expires!
