  We examine the AdS Higgs phenomenon for spin-1 fields, and demonstrate that
graviphotons pick up a dynamically generated mass in AdS_4, once matter
boundary conditions are relaxed. We perform an explicit one-loop calculation of
the graviphoton mass, and compare this result with the mass generated for the
graviton in AdS. In this manner, we obtain a condition for unbroken
supersymmetry. With this condition, we examine both N=2 and N=4 gauged
supergravities coupled to matter multiplets, and find that for both cases the
ratio between dynamically generated graviton and graviphoton masses is
consistent with unbroken supersymmetry.
