If I use the jbpm-console to access a user task list from a machine inside our LAN I only need to enter my user credentials once at login.

However, if I do the same thing via a machine accessing the server from outside the LAN (i.e across a WAN) I enter my credentials at login time (as expected) but when I either start a new task or complete a user action on an existing task I am prompted for my login credentials once again.

Can anyone tell me what step I've missed? Presumably  I need to set up an authentication mapping for the Human Task service (or something!).

(I'm sure I've seem another post on this topic but can't refind it.)

Thanks
