Longford Town collected an important point on the road after Tunde Owolabi’s strike marked off Aaron Dobbs opener.
Dobbs gave Town the lead on 11 minutes in controversial circumstances, Dylan Grimes crashed a shot off the bar from just outside the box.
The ball fell to Aaron Dobbs who calmly put it past keeper Mark McGinley. All the players stopped as referee’s assistant had raised his flag, only for referee Ben Connolly to award the goal.
Harps were level six minutes later Barry McNamee’s reverse pass was collected by Owolabi who shook off his marker and slotted the ball home.
Harps had the better of the chance but squandered a penalty five minutes into the second half, their best chance to take the lead.
The draw see’s Longford move to nine points as they remain bottom of the table, four points behind Waterford who drew with St. Pats.
