Identity Broker agent a bit bewildering - which end-points?

When creating a Identity Broker agent, you get two rather bewildering "endpoint configuration" text boxes.

Now I know what values should go in there, but most people are not going to have any idea. I note that you get suggested values when you just submit, but a lot of people are going to baulk at this point.

Might it be a good idea to prepopulate with the default values?
