Working within a five-dimensional consistent truncation of type IIB supergravity dimensionally reduced on T^{1,1}, we consider supersymmetry breaking solutions with the asymptotics of the supersymmetric KS background. There exists a two-parameter family of such solutions. Within this family, we show that those (and only those) solutions related to antiD-branes at the tip of the conifold correspond to dual field theory vacua where a goldstino mode is present and the supercurrent Ward identities hold. Our findings do not depend on the IR singularity of the dual backgrounds, nor on its resolution. As such, they provide independent evidence for the existence of superysymmetry breaking vacua in the conifold cascading gauge theory.
