Map an NT Domain Admin Group to a Unix Group
A Samba Server can be configured as a PDC to map a Windows NT
domain admin group to the Unix group.
Modify the smb.conf file to set the global parameter named domain
admin group to point to the Unix admin group and user. Example:
[global]
domain admin group = root @adm
In this example, a group called “adm” should be created by the user in
the /etc/group file.
Map an NT Domain Guest Group to a Unix Group
A Samba Server can be configured as a PDC to map a Windows NT
domain guest group to the Unix group.
Modify the smb.conf file to set the global parameter named domain
guest group to point to the Unix guest built-in group and user.
Example:
[global]
domain guest group = guest @guest
In this example, a group called “guest” should be created by the user in
the /etc/group file.
