2.2.2.3 Federated Authentication Information

After the server receives a Login message that states that the client intends to use a federated authentication token from a specific client library that needs additional information from the server to generate that token, if the server supports federated authentication that uses that client library, the server responds to the client with a message. This message contains a Federated Authentication Information Token that provides the information necessary for the client to generate a federated authentication token. If the server determines that no information is required for this particular client library, the server does not send the information token. For more details, see section 2.2.7.12.
