Transparent user authentication

Content Gateway supports both transparent (Single Sign-On) and interactive (prompted) authentication. Transparent authentication is supported with Integrated Windows Authentication and Legacy NTLM. Some browsers provide only limited

support. See Browser limitations.

On Windows networks, Single Sign-On allows users to sign on only once so that they can transparently access all authorized network resources. Therefore, if a user has already logged on to the Windows network successfully, the credentials specified during Windows logon are used for proxy authentication and the user is not prompted again for a username and password.

Interactive authentication is supported in networks that are not configured for Single Sign-On and for use with browsers that don’t support Single Sign-On. With interactive authentication, users are prompted for credentials before they can access content through Content Gateway.
