I have added a SAML IdP and can successfully authenticate.

I have also added some mappings to map assertions in the SAML token to database fields.  
I can see that the SAML token is in the POST back to keycloak contains the assertions i am after, but nothing is appearing in Keycloak.

How do I go about debugging this scenario? I'm new to the product. I've switched to DEBUG mode, but I'm not seeing anything definitive.

Thanks,

Matthew
