• Click Mounts in left hand pane
• Enter ou=Mounts,dc=lll,dc=lu as a search base

N.B. It is expected that the template setting automatically changes from RFC 2307 to Custom as soon as you change one of the setting.

On some newer version of MacOS, you may need to click on the "Search Policy" Icon at the top of the "Directory Utility" (only clickable if currently no service is being edited: click Ok or Cancel to dismiss if you are editing a service), and then add the newly defined service to the list.

Testing

Now is time for testing.

• Open a terminal by calling Applications/Utilities/Terminal in file manager
• In terminal, enter dscl localhost list /Search/Users

. This displays a list of all users known by the macintosh. If everything worked, it should include all users from the server's LDAP database.

• If all users are included, log out, and log back in as one of the server users (you need to click "Other users" at the login window, then enter its name). It's expected that the login process is slow, as we have not yet set up mounting of /home.
• If login was successful, clean away its temporary home directory (if the system created one)
