[Samba] PATCH: Fix example of server role parameter in smb.conf manpage (WAS: invalid value 'netbios backup domain controller')

[Marc Muehlfeld]

Hello Andrew,

while reading your and Rowlands discussion about recommending or not the
'server role' parameter on other machines than DCs, I saw, that the
smb.conf manpage example says

> Example: server role = DOMAIN CONTROLLER

However, correct is

> Example: server role = ACTIVE DIRECTORY DOMAIN CONTROLLER


Attached a fix. Please review and push, if OK.
Thanks.


Regards,
Marc
