Connection with keycloak from bloomreach by using saml


I want to connect bloomreach with keyacloak by using saml protocol, I have followed some links below :-:

I have added dependencies and security classes and also configured client in keycloak with saml protocol, now when I hit {baseurl}/cms then it redirects to keycloak but keycloak fails. Keycloak always says :-
13:34:12,314 WARN [] (default task-6) type=LOGIN_ERROR, realmId=my_realm, clientId=null, userId=null, ipAddress=, error=client_not_found, reason=Cannot_match_source_hash

Not sure how much data and what data I should pass through bloomreach.

Any help will be appreciated.
