If you are using supported third-party products, you must determine if any changes are needed in those products to support form-based authentication.

Cognos, for example, does not use the Windchill servlet engine and authenticating code; therefore, the built-in Windchill servlet-engine-based form-based-authentication cannot be used as a consistent single-sign-on between Windchill and Cognos. In a normal configuration, Cognos latches onto REMOTE_USER directly. If REMOTE_USER is not set, then Cognos requires special configuration to use form-based authentication.
