Kris and Johan,

Both of you have not appended your smb.conf files.  Maybe doing that
would help as well.

- From what I am seeing, the pam stack Kris gave was authenticating via
winbind which would use either plaintext, lanman, ntlm or ntlmv2 and not
configured to authenticate using kerberos.  The plaintext password
authentication is pretty insecure and this is what I suspect your setup
is attempting to use.  Win 2008 has that disabled by default as well as
(afaik) lanman and ntlm.  If you plan on using winbind to authenticate,
you will likely need to add the following directive in the [global]
section of your smb.conf file:

client ntlmv2 auth = yes

You may then need to restart winbindd and smbd (hell, you could restart
the whole machine if you felt like it).  Tell us if this works out for you.
