Since I had a similar issue, make sure that DISPLAY is unset when you ssh on user_b at localhost. The variable is passed to the PA clients (at least), and they can't connect to the system instance and try to connect on user_a at localhost somehow, and fail (as it seems to me). PA should probably be more verbose about this issue, I probably had it in the past, but couldn't find the reason. cheers, -- Marc-Andr? Lureau
