Two form fields with identical label when creating/updating a connector or delegated directory

The form to create or update a connector or a delegated directory has two fields labelled "User DN". One of them is in the second tab, and has the following description: "Connect to the directory server using the supplied username". The second one is in the third tab and has this description: "This value is used in addition to the base DN when searching and loading users. An example is ou=Users. If no value is supplied, the subtree search will start from the base DN".

Note that the syntax for the value of these fields is different. In the first case, it must by a fully qualified DN, while in the second case, it is just a component that is prepended to the base DN.

It would be nice to have different labels for these two fields to reduce confusion.
