We study gaugino condensation in the presence of an intermediate mass scale in the hidden sector. S duality is imposed as an approximate symmetry of the effective supergravity theory. Furthermore, we include in the Kaehler potential the renormalization of the gauge coupling and the one-loop threshold corrections at the intermediate scale. It is shown that confinement is indeed achieved. Furthermore, a new running behavior of the dilaton arises which we attribute to S duality. We also discuss the effects of the intermediate scale, and possible phenomenological implications of this model. {copyright} {ital 1997} {ital The American Physical Society}
