We are attempting to configure our SLES 11 SP3 server to use LDAP for user authentication and active directory.

We currently use Samba4 to manage users and groups, which then control permissions for a number of simple network fileshares on the server, as well as Windows NT logon for our domain computers (no roaming profiles). Our Samba installation uses smbpasswd for the backend authentication.

My question then is, how can I go about configuring our server to import the Samba users/passwords/groups into LDAP and have LDAP take ownership of being the domain controller?
