a29jw (a29jw) asked a question.
we are setting up and IDP, we exchanged the "IdP Issuer URI", "IdP Single Sign-On URL" and the certificate. the certificate has expired, it still lets me save the IDP.
then trying to use it for federated login, we get this error:
"Unable to validate incoming SAML Assertion"
"The Issuer in the SAML response did not match the Issuer configured for the Identity Provider."
any help?

Hi Tomer,
Invalid issuer in the Assertion/Response suggests that the issuer value in the SAML assertion does not match the entity ID.
To further investigate this issue, please open a new ticket at Okta Support and our engineering team will gladly provide you assistance.
