About the HTTP Basic Authentication Attribute

HTTP basic authentication can be set in the Gateway service.

Web sites may be protected with HTTP Basic Authentication, requiring visitors to enter a username and password before viewing the site (the HTTP response code is 401 and WWW-authenticate: BASIC). Portal Server can save the username and password so that users need not re-enter their credentials when they revisit BASIC-protected web sites. These credentials are stored in the user profile on the directory server.

This setting does not determine whether or not a user may visit BASIC-protected sites, but only whether the credentials the user enters are saved in the user\qs profile.

This setting applies to all web sites that the user is permitted to access (that is, HTTP basic authentication caching cannot be enabled for some sites and disabled for others).

Browsing to URLs served by Microsoft\qs Internet Information Server (IIS) protected by Windows NT challenge/response (HTTP response code 401, WWW-Authenticate: NTLM) instead of BASIC authentication is not supported.

You can also enable single sign-on using the Access Control service in the administration console.
