[satosa-users] Problem with Dynamics 365 Portal

Hello, Our SP is a Dynamics 365 Portal, S2S as SAML2SAML proxy, backend gets metadata from SWAMID, frontend act as IdP for our portal. Getting the following error, it always stop at “returning attributes”. Could it possibly be a problem with self-signed SSL certificate that Microsoft CRM Portal does not accept or is any parties not accepting SHA256? Or is there anything else that I forgot to configure? Thanks for any help from you guys. The end of the debug log is below.
