One of our client had certification rollover at their adfs implementation. After that they are no longer able to login.
The main question we are facing is, before this rollover we never used certificates in our saml authentication.
We have set expressjs with passport passport-saml and we never use any cert for it. It was working before but now it got stopped.
I searched and found that at our end we need to updated the certificates received from federationmetadata from their adfs.
Questions:
Any possible reasons why it might have stopped working ? How was it working before without certificates if we need to update certificates now ?
