Monica has configured her IBM Domino Web server for federated login using SAML, but when she starts the server, the server console displays the following message: HTTP Server: SAML configuration error. SAML is enabled for server [IdP], but no active IdP configuration could be loaded. Monica examines the IdP Configuration document, and it appears to be OK. What else should she check?
A. ID Vault configuration document
B. Security Tab of the Server configuration document
C. Federated Login tab of the Policy settings document
D. Domino Web Engine tab of the Server document (or Internet Site document, if used)
