The NetSentron allows the administrator to set three different types of Authentication:
No authentication by the user to the NetSentron for accessing the Internet.
NetSentron Authentication will allow manually redirecting of each user through the NetSentron proxy server. Selecting this setting will prompt each user for a user name and password when opening a browser. Useful a Windows Server with Active Directory is not present within the company to authenticate the users.
Active Directory Authentication
The NetSentron is capable of authenticating users against an Active Directory server to validate their username and password. It’s supported on Windows Server 2000 and Server 2003. This can be done in two ways: single sign on where any machine already logged on to the Domain will automatically pass its credentials on to the NetSentron; or, if not logged in, a dialog will come up asking for a valid username and password.
