Hello, it depends by the implementation of the UI: after you're done typing the JNDI binding(s) in "Entries" field, just push on the "Enter" keyboard button. The UI will display a text rounded box just below the field with the entry provided. Eventually, you can proceed by clicking on "Add" button. It is not very intuitive. Hope this will help.
Thanks this works. I agree "It is not very intuitive"
