System_CAPS_pubmethodLogonUser(String, String, String)

The IAuthenticationExtension interface in Reporting Services enables your security extension to specify a custom way for the report server to authenticate users. To create an authentication extension class, implement IAuthenticationExtension.

Your authentication extension should provide implementations for the LogonUser, GetUserInfo, and IsValidPrincipalName methods. Implementing IAuthenticationExtension enables your security extension to validate user credentials against a specified authority and enables the report server to access user information.

The primary way in which you can implement a custom authentication extension is through the use of Forms authentication. For more information, see "Forms Authentication Provider" in your .NET Framework Developer's Guide.
