We prove that the Brauer-Manin obstruction is the only obstruction to the existence of integral points on affine varieties over global fields of positive characteristic p. More precisely, we show that the only obstructions come from \'etale covers of exponent p or, alternatively, from flat covers coming from torsors under connected group schemes of exponent p (joint work with F. Voloch).
