54 Server Config – Personal Firewall Rules

3.4 User Objects

The User Objects tab allows you to create User and User Group objects, which may be employed in
rule sets. Click New … to open the Edit/Create User Object dialog:
An user object is automatically created when a connection attempt is processed by the firewall. The
object is then inserted into the corresponding rule.
In the User/Group list, the Microsoft Windows domain users and groups known to the Barracuda NG
Firewall are available for selection. Local user/group information is displayed in the list first. If the
Windows workstation is a member of a Microsoft Windows domain, domain user/group information
may be retrieved from the Active Directory server by clicking Update.

Irrespective of the operating systems language version installed on the workstation, the following users will always be
displayed in English:
• NT AUTHORITY\SYSTEM
• NT AUTHORITY\LOCAL SERVICE
• NT AUTHORITY\NETWORK SERVICE
• NT AUTHORITY\NETWORK
The internal firewall engine will transform these names to the appropriate language version. Do not insert them in an-
other language manually.
