OK, Github's code search simply sucks. But the issue (and code
reference) below explains the meaning and also confirms my guess that
you've probably misunderstood/botched your IDP upgrade by using
completly new/different keys from the installer. Copying over your old
IDPv3 keys should fix that. Or redoing your IDPv4 instance, really,
because who knows how many other things you've forgotten to carry over?
"If you search for cert_not_accepted in esaml, you will find that
this error occurs when the cert fingerprint is not trusted. It is
possible for this to happen when the certificate in the idp metadata
file specified in the config does not match the one coming through
the SAML response."
