Barracuda Web Filter Release 3.3
58 Chapter 4: Managing Users and Groups
1.
A user logs into their domain and is authenticated by the domain controller.
2. The DC Agent keeps a record of the newly authenticated user.
3. The Session Monitor polls the DC Agent (every 15 seconds by default) and retrieves the latest
list of authenticated users.
4. The user attempts to access a Web site that is blocked by the Barracuda Web Filter. The
Barracuda Web Filter prompts the user to enter account information that will allow them to
override the filter.
5. The user enters account information, and the Barracuda Web Filter determines if an exception
policy exists that allows the account to override the filter. If an exception policy does exist, the
user is allowed to access the previously blocked content.
