[Samba] Problem using ADS

[Dave Jones]

Hi,
I have configured samba to authenticate against a windows 2003 AD. There is
no error joining to the domain ..
If I try to access any share using smbclient using an existing user account
from the AD, it returns an error "NT_STATUS_LOGON_FAILURE".
On adding the same user to local machine (/etc/passwd), the smbclient logs
in and displays all information properly.

Is this the usual behavior or did I forget configuring something ?
