I have gone through example provided for OIDC application and it worked perfectly fine. Based on SAML documentation available in Keycloak below is my understanding 1) Need to provide implementation for SamlConfigResolver's resolve() method in SAML application. 2) Mention above implementation in web.xml. For this verification I am trying to customize post-with-signature example. I have added keycloak-saml-adapter-core and keycloak-adapter-spi dependancies in pom.xml. I just write an SOP statement in resolve method. When I run, I get java.lang.NullPointerException Please share your thoughts on following points: 1) Is my above understanding is correct? In case if I am missing something then please let me know. 2) Is there any other approach with which we can achieve this behavior?
