Re: [keycloak-user] Connection Reset using LDAPS

In my Keycloak 2.2.1 environment we see continuous yet erratic errors in connecting to AD via LDAPS. For example, if I search for a user I may get a general server error and then click search again and receive results. I tried adding the following to the startup: -Djdk.tls.client.protocols=TLSv1 Based on an article regarding java8 and AD but it does not appear to have made any difference. The error: 14:56:20,143 ERROR [org.keycloak.federation.ldap.idm.store.ldap.LDAPOperationManager] (default task-21) Could not query server using DN [OU=redacted,DC= redacted,DC=com] and filter
