Northern Ireland held a three-point margin over Bosnia heading into the fixture, and advantage in the head-to-head thanks to February's dramatic 3-2 win at Inver Park.
Bosnia made a bright start as Marija Milinkovic headed wide in the early stages, before the midfielder had another effort cleared away by Holloway and Krajsumovic smashed the rebound wide.
Northern Ireland grew into the game and their first attack came when Danielle Maxwell's cross was inches away from Lauren Wade, and Magill was also close to the opener when she tried to slide onto Joely Andrews' touch in the area.
Magill had an even better chance when Megan Bell found the forward in the area, but Bosnia keeper Almina Hodzic made herself big to deny the Northern Ireland captain.
Minutes later, Magill was not to be denied when she raced onto Holloway's perfect through ball and the Birmingham City striker kept her composure to poke the ball into the bottom corner in the 23rd minute.
However, Northern Ireland's lead lasted only six minutes and the hosts drew level when Krajsumovic got in behind Holloway and beat Ellie Mason to the ball.
In sweltering heat, the CSKA Moscow winger kept her cool to slot the ball beyond Jackie Burns.
