With 20 minutes played, Samaras ran to the goal-line and sent a sharp cross into the six-yard area, but slightly over-cooked it and McDonald was left wanting.
Sodje had a good chance to grab his second goal moments after the break, but the striker lashed his left-foot effort over the crossbar from just inside the penalty area.
Conway was without doubt United's most dangerous player and he hit a 20-yard left-footed drive just over after spinning away from Eggert Jonsson on the edge of the area.
