SSO User access issue

I have one user who is having difficulty accessing the system via SSO. We have attempted deleting the account and opening a new one. The browser data has been cleared but still had issues. See attached for the error message. Is this related to the Esdat end of the verification or MS Azure?  Sent from ESdat

This is on the client's IT security side. We suggest contacting the IT team to assist with the SSO log-in issue.
