Barracuda Web Security Gateway: Authenticate Users
How are users authenticated?
The Barracuda Web Security Gateway supports three types of authentication:
For Windows domains, the Barracuda Web Security Gateway has Barracuda DC Agent software to install on Windows Domain Controllers. This software monitors Windows login events and maps Windows user names and IP addresses to the Barracuda Web Security Gateway to transparently apply user policy.
When users try to access a blocked resource, the Barracuda Web Security Gateway displays a page that requests a username and password. This method doesn’t require the Barracuda DC Agent or configuring users’ browsers.
If configured in forward proxy mode, the Barracuda Web Security Gateway can use standard proxy authentication in which browsers send the authentication credentials in the HTTP headers. This form of authentication can require a one-time configuration of users’ web browsers. Proxy authentication is not compatible with the Barracuda Web Security Gateway while running in transparent mode.
