Question Authenticating Samba and Win2K NT_STATUS_IO_TIMEOUT

Hello crew,

I'm having troubles with authenticating a linux samba client to a win2k domain. Without creating local users I want to be able to log on using a user and pass valid only in the windows domain.

Somehow I seem to be stuck on the last part:

When I log in with correct user and correct pass:

Jan 14 16:29:03 sandbox pam_winbind[2632]: pam_winbind: pam_sm_authenticate (flags: 0x0000)
Jan 14 16:29:07 sandbox pam_winbind[2632]: Verify user `testuser'
Jan 14 16:29:17 sandbox pam_winbind[2632]: request failed: NT_STATUS_IO_TIMEOUT, PAM error was System error (4), NT error was NT_STATUS_IO_TIMEOUT
Jan 14 16:29:17 sandbox pam_winbind[2632]: internal module error (retval = 4, user = `testuser')

When I login using a WRONG password:

Jan 14 16:31:33 sandbox pam_winbind[2675]: pam_winbind: pam_sm_authenticate (flags: 0x0000)
Jan 14 16:31:35 sandbox pam_winbind[2675]: Verify user `testuser'
Jan 14 16:31:35 sandbox pam_winbind[2675]: request failed: Wrong Password, PAM error was Authentication failure (7), NT error was NT_STATUS_WRONG_PASSWORD
Jan 14 16:31:35 sandbox pam_winbind[2675]: user `testuser' denied access (incorrect password or invalid membership)

When I login using `wronguser`:

Jan 14 17:38:43 sandbox pam_winbind[2928]: pam_winbind: pam_sm_authenticate (flags: 0x0000)
Jan 14 17:38:45 sandbox pam_winbind[2928]: Verify user `wronguser'
Jan 14 17:38:45 sandbox pam_winbind[2928]: request failed: No such user, PAM error was User not known to the underlying authentication module (10), NT error was NT_STATUS_NO_SUCH_USER
Jan 14 17:38:45 sandbox pam_winbind[2928]: user `wronguser' not found

Testing the authentication using `kinit` works perfectly. `wbinfo -u` and `wbinfo -g` produce all users and groups in domain. `getent passwd` gives me only the local machines listings. I'm working with a fresh debian install. All packages are installed `out of the box`. I'm very willing to supply more info but I thought posting the entire config upfront is a little too much. I'm using Linux sandbox 2.6.18-5-686 #1 SMP Mon Dec 24 16:41:07 UTC 2007 i686 GNU/Linux
and Samba Version 3.0.24
