For Samba to be able to work as a PDC, some modifications are needed in its main configuration
file. Select the THREE options below that show the required actions for this task.

A.
The Samba server has to be a logon server. This can be configured by the domain logons
directive.

B.
The Samba server needs to have the logon and the account creation scripts, to properly setup
the PDC environment.

C.
The Samba server must be a Domain Master Browser. To configure this, the domain master
directive must be set to yes.

D.
The time server = yes directive needs to be configured, so Samba will behave as a WINS
server and also a Time server.

E.
The security = user directive must be set.
