[keycloak-user] ldaps configuration --> Bug or regression with ldap connection ulr

[Dmitry Telegin]

This looks like an unconfigured SSL truststore. Could it be that you have configured it in standalone.xml instead of standalone-ha.xml (which is used by default in Docker image for Keycloak 4.5.0+)?
