The Gleason problem is solved on real analytic pseudoconvex domains in ${\mathbf{C}}^2$. In this case the weakly pseudoconvex points can be a two-dimensional subset of the boundary. To reduce the Gleason problem to a $\bar{\partial }$ question it is shown that the set of Kohn-Nirenberg points is at most one-dimensional. In fact, except for a one-dimensional subset, the weakly pseudoconvex boundary points are $R$-points as studied by Range and therefore allow local sup-norm estimates for $\bar{\partial }$.
