I have a similar problem with Samba 3.4.0, running on an Ubuntu server. I have seen this problem reported a number of times (on this list and elsewhere), but I have not seen any solution for it yet (still searching!). It seems to affect a number of people, but not all - some setups with Windows 7 work fine. > I read in a forum that could be a cache password problem related with > nscd, now i disabled service ncsd and enable winbind. I noticed after a trust relationship had broken that this machine's trust password had changed on the same day. I assume this is linked, though I am not sure who initiates this password change - is it Samba or is it the Windows 7 computer ? Here is a scenario I noticed : 1. User logs on fine in the morning ; 2. The pdb entry for that user suggests that the machine account password gets changed after the user has logged in ; 3. After a restart, the machine complains of a broken trust relationship. For instance here is the entry for a machine that was reported to have lost it's trust relation ship on Friday 2nd of July. The 'Password last set' field corresponds roughly to the time the user logged on. After restart, the trust relationship was broken : # pdbedit -Lv -u ct405$ Unix username: CT405$ NT username: Account Flags: [W ] User SID: S-1-5-21-4063849384-1695801231-3426977757-1029 Primary Group SID: S-1-5-21-4063849384-1695801231-3426977757-513 Full Name: CT405$ Home Directory: \\xxxx\ct405_ HomeDir Drive: H: Logon Script: ct405_.bat Profile Path: \\xxxx\Profiles\ct405_ Domain: xxxxxx Account desc: Workstations: Munged dial: Logon time: 0 Logoff time: never Kickoff time: never Password last set: Fri, 02 Jul 2010 09:20:39 BST Password can change: Fri, 02 Jul 2010 09:20:39 BST Password must change: never Last bad password : 0 Bad password count : 0 Logon hours : FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF I don't know if any of this can help people suggest a fix. If you have ideas of things I could try, or would like me to run some tests, I will be more than happy to oblige !

From: Ufficiotecnico Acknow Srl on 6 Jul 2010 08:40 A strange thing is that i have three domain with samba 3 and windows 7 client, in two of this scenario no problem: opensuse + samba samba3-3.3.10-40 and centos + samba samba3-3.3.12-40 while with sles 10 and samba3-3.2.15-40 the problem persist, the field password last set in the scenario with no problem is 1 month earlier while in the problematic domain is setted with the date of login.
