I assume that you're typing in the correct password; that of the user
running gksu.

The problem's probably that you have to extract Xauthority from the
gksuing user and merge it into the Xauthority of the gksu'd user. I'm
about to board a flight so I'll have to post a fuller answer later if
this info's not enough.
