Proxy Authentication

Web Safety can be configured to require connecting users to authenticate themselves. There are several modes of proxy authentication supported.

IP Address Labelling	Pseudo Auth	Pseudo authentication (assigning of labels) to IP addresses in your network.
Local Users Database	Explicit Auth	Authentication using the manually managed list of user names and passwords stored in a file on the proxy server using Basic Authentication.
Captive Portal	Pseudo Auth	Authentication of users based on IP addresses they connect from.
Radius Auth	Explicit Proxy Auth	Authentication using existing Radius server deployed in your network.
Microsoft Active Directory	Explicit Proxy Auth	Built-in Microsoft Windows single-sign-on proxy authentication using the Negotiate authentication scheme (both Kerberos and NTLM) or Basic LDAP authentication with users from your Active Directory environment. Recommended mode.

All aspects of proxy authentication are configured in Squid / Auth node in the Admin UI.
