Samba Logon Hours

Hi All,

This may be me being completely dense. I have setup a Samba PDC. I am doing this in stages since I had problems trying to use ldap. I have used tdbsam to get a basic setup running. All works fine. All I want to know is can I add logon hours and if so, how do I change them?

Or do I have to use LDAP for this?
