We consider the minimal supersymmetric extension of the Standard Model allowing both Dirac and Majorana gauginos. The Dirac masses are obtained by adding extra chiral multiplets. We discuss different scenarios where the LSP is either a bino (in which case it can be a Dirac fermion) or bino-higgsino/wino mixtures and point out in each case the peculiarity of the model with respect to dark matter detection experiments.
