CAS Service Validate failure not correctly logged
Using LL::NG as CAS client, when there is an issue with Service Ticket validation, we got this log:
[Thu Mar 25 16:15:34 2021] [LLNG:17169] [error] Failed to validate Service Ticket ST-7250d494-bdd1-46ec-9ed5-83006202c0f4: HASH(0x463c168)
We should display the content of the XML cas:authenticationFailure
node.
