Hi Gluu Team, We have established the trust relation between our moodle application as SP and Gluu as IDP successfully. We have generated metadata for onboarding JumpCloud IdP on Gluu setup to integrated this in our application service provider. After that when we have reestablished the trust relation between our moodle application as SP and Gluu as IDP but we got error Failed to authenticate. Kindly suggest us what could be the reason for the flowing error log. 2018-01-27 07:38:58,256 ERROR [qtp212628335-12] [org.xdi.oxauth.service.external.ExternalAuthenticationService]
