1. Enable RMAD connector.
2. Specify RMAD server settings. Domain settings are left blank.
3. Disable RMAD connector.
4. Click Apply.
5. Try and run a search. Error banner is likely:

Service cannot be started. Cannot process argument because the value of the argument "userName" is not valid. Change the value of "userName" argument and run the operation again."
