|RegisteredModules||Gets a list of authentication modules that are registered with the authentication manager.|
|Authenticate||Calls each registered authentication module to find the first module that can respond to the authentication request.|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|

|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|PreAuthenticate||Preauthenticates a request.|
|Register||Registers an authentication module with the authentication manager.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
|Unregister(IAuthenticationModule)||Removes the specified authentication module from the list of registered modules.|
|Unregister(String)||Removes authentication modules with the specified authentication scheme from the list of registered modules.|
is a static class that manages the authentication modules that an application uses. When a request is made to protected resources, the calls the Authenticate method to get an Authorization instance to use in subsequent requests.
The 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 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.
The Kerberos and negotiate authentication type is not supported on Windows 95/98 or Windows NT 4.0.
