[Samba] Samba 3.0.2x Wbinfo -t ShowslJoined, but -u and -g fail to retrieve anything

[mark at truenorth.nu]

Folks,

I'm working on troubleshooting an installation where Samba 3.0.2x is joined to the domain.  If I issue the command "wbinfo -t" it shows the secret is correct.  If issues "wbinfo -u" or "wbinfo -g" they give an error about being unable to retrieve any users or groups.

Just to test whether I could authenticate against the domain, I tried using ntlm_auth with the following commands and was unable to authenticate: 

> /etc/raddb # ntlm_auth --debuglevel 10 --username=<correct name here> --domain=<correct domain here> --password '<correct password here>'

I'm not working on my own AD network, so I'm not familier with all the settings or configuration for the domain.  What domain settings or configurations might allow Samba to join, but prevent the listing of users and groups? 

Does anyone have any suggestions about what might be causing these errors?

Thanks in advance for your help.
