You can also test both non-ssl and ssl connection to public ldap server from this screen, just click on the Test Connection links to open the connection. Test connection to public ldap servers requires internet connection and will work only if the servers are available at the time of connection. You can modify the test public servers from the Options |Preferences |Test Connections
