SAML Login with Azure Authentication Failed

Hi,

I am getting Authentication failed error while using SAML 2.0 in checkmk CEE . It was working before, but it stopped working now. Not sure. I have checked the configuration and everything looks good. What am I missing here?

So, the issue has been resolved now. It seems after the CheckMK update, SAML was not authenticating the old users. I had to remove those users manually. Then they were able to re-authenticate with SAML again.
