AuthenticationManager is a static class that manages the authentication modules that an application uses. When a request is made to protected resources, the AuthenticationManager calls the Authenticate method to get an Authorization instance to use in subsequent requests.

The AuthenticationManager queries each registered authentication module by calling the IAuthenticationModule.Authenticate method for each module. The first authentication module to return an Authorization instance is used to authenticate the request.

Modules that provide the basic, digest, negotiate, NTLM, and Kerberos authentication types are registered with the AuthenticationManager by default. Additional authentication modules that implement the IAuthenticationModule interface can be added using the Register method. Authentication modules are called in the order in which they were added to the list.

NoteNote

The Kerberos and negotiate authentication type is not supported on Windows 95/98 or Windows NT 4.0.

No code example is currently available or this language may not be supported.
