samba - Aug 2007 - password server DOMDC1 rejected the password: NT_STATUS_LOGON_FAILURE

Hello list,

I have trouble with a smb configuration that worked fine before I upgraded my
samba to the latest stable release.
I used samba 3.0.23c (Slackware11) and now I'm using samba 3.0.25b
(Slackware12).

The error/failure looks like this:
I'm trying to connect to my HOME service and I fail. The log produces only
this:
[2007/08/13 10:29:33, 1] auth/auth_server.c:check_smbserver_security(357)
  password server DOMDC1 rejected the password: NT_STATUS_LOGON_FAILURE

What is wrong now after the upgrade? I swear the config file worked OK before!

here the results of testparm:

hello list,

I played around with my own problem and it looks like something has
changed in the way users get authenticated from version 3.0.23c to
3.0.25b.

It would help me a lot if someone could point me out to these changes (or
maybe it is bug).

I installed the former version that I had (3.0.23c) and it worked OK out
of the box. The same configuration did not work with 3.0.25b. I changed
the security to "domain" but again this did not work, either.

The picture that I get right now of the new version is that authenticating
users to remote password server is broken. Can anyone verify this?

Thanks for your help.

Michael
