Hello, I am getting the below when testing authentication with LDAPS. The “Test Connection” button is successful, but the “Test Authentication” throws the below in the server.log file. When I remove LDAPS and replace with just LDAP, both are successful. I have the truststore SPI setup, i’ve recreated the Java truststore.jks file multiple times. Looking for guidance. 2021-05-27 15:25:59,837 ERROR [org.keycloak.services] (default task-1) KC-SERVICES0055: Error when authenticating to LDAP: simple bind failed: domain\_controller:636:
