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 ?
