Web application profiles provide single sign-on and translation control for Web applications that use Windows NTLM authentication (v1 and v2 are both supported), or basic authentication.
With a Web application that uses Windows NTLM authentication, access is granted only to users whose Windows credentials can be verified. Support for NTLM is built into Microsoft IIS (Internet-based services for Windows machines) and supported in all the appliance supported browsers.
Basic authentication is supported on a wide variety of platforms (note, however, that it sends passwords in the clear across the network).
You can also configure the Web proxy service in AMC to support forms-based authentication, in which users authenticate by filling out a standard HTML form Web using any combination of browser and Web server. Creating Forms-Based Dynamic Single Sign-On Profiles for more information.
