[keycloak-dev] passing saml authentication context to custom authenticator

Hi Guys, Is there a way to get SAML authentication context in custom authenticators? In the code, looks like it's not possible since it is not set anywhere in AuthenticationSessionModel. So if this is true, what would be the best way to pass it considering it may contain multiple information? It can be set as client session note just like other values from SAML request, but there has to be a way to serialize and de-serialize it since it's a complex object. What approach do you recommend? Thanks, Gideon
