backshifting - So that I can vs So that I may



In the cases below, do I always have to use 'may' instead of 'can'? Both sound correct to me however, I had read explanations that said that 'may' should be used after 'so that'.


I came earlier so that I may help them. I came earlier so that I can help them.


Please be on time so that we may leave before 5. Please be on time so that we can leave before 5.


Thanks
