Are you getting just those 2 errors in the log or any more? Please share other errors also if there are somemore.

If those are only 2 then See:SAML Grammar response Error/Warning

Hi anushap40132887

We are getting the same error in the logs, but SAML authentication is working fine. Could you please let us know if you were able to find resolution of this issue?


Thanks cqsapientu69896437 for the reply. I have removed the saml configuration and reconfigured again and it started working for me after few hours.
