I'm researching on Samba and have created a PDC using it. I have created user and computer accounts and things are working. I'm having problems, however, in finding how to create groups and add users to them. Samba apparently doesn't create AD default groups like "Domain Users" or "Domain Admins". Does it use Unix groups for that or I have to create them using some Samba tool?
Are these groups "searchable" in Windows workstations as users are (or like when using AD)?
I'm running CentOS 6.7 and Samba 3.6.23.
I'm using tdbsam to store user data.
