Using the administrative console, configure your server settings to enable the WS-Trust protocol.
  1. Go to System > Server > Protocol Settings.
  2. On the Federation Info tab, enter your SAML federation IDs unless these IDs are already established for the corresponding browser-based SSO protocols.

    Identifiers are required for both SAML 2.0 and SAML 1.x to enable the STS to issue either type of token when requested. If you have not established a federation ID for either of these protocols or do not expect to use one or the other, enter a placeholder in any format and reconfigure later.
