LDAP search query timeout

The appliance is having trouble communicating with your Kerberos server and has timed out waiting for a response. Specifically, the appliance is unable to auto-detect the LDAP authentication DN field. Check your Kerberos server and firewall settings to ensure that they are communicating on the proper ports and that those ports are properly configured on your firewall, and then re-test the Active Directory settings by clicking Verify Settings on the System: Active Directory page.
