Details
This message is displayed by "WSO2 Identity Server" which is an application bundled with the Ellucian Ethos Identity (EEI) product which is used for Single Sign-On (SSO) to Banner applications. It functions as a SAML to CAS sign-on gateway which is why it states the CAS service provider is not authorized.
This error can occur for a few reasons.
- The most common issue is the Ellucian Ethos Identity (EEI) database connectivity may be failing due to an expired password, database connectivity or similar issue.
- It is also possible for part of the EEI service to be in a failed state.
- One of the "CAS" Banner Apps may be misconfigured.
