  We present a novel scheme where Dirac neutrinos are realized even if lepton
number violating Majorana mass terms are present. The setup is the
Randall-Sundrum framework with bulk right handed neutrinos. Bulk mass terms of
both Majorana and Dirac type are considered. It is shown that massless zero
mode solutions exist when the bulk Dirac mass term is set to zero. In this
limit, it is found that the effective 4D small neutrino mass is primarily of
Dirac nature with the Majorana type contributions being negligible.
Interestingly, this scenario is very similar to the one known with flat extra
dimensions. Neutrino phenomenology is discussed by fitting both charged lepton
masses and neutrino masses simultaneously. A single Higgs localised on the IR
brane is highly constrained as unnaturally large Yukawa couplings are required
to fit charged lepton masses. A simple extension with two Higgs doublets is
presented which facilitates a proper fit for the lepton masses.
