Hello everyone,
Done two testing:
-
Docker jboss/keycloak image, user federation/ldap/active directory works fine.
-
Standalone mode in local machine:
After download and setup KeyCloak in my local machine running in standalone mode, got this error for test connection in User Federation/LDAP/Active Directory: Error when trying to connect to LDAP. Here is the detail error in the server log file:

I’m not a Java developer, so the error message doesn’t help. I did a lot of researching about the error message but didn’t find a solution yet.
Could be that I miss configured something?
Appreciate your help.
