Patch from metze to add what he feels is the correct semantics for a Domain
Controller. As we have had a number of attempts at this over the last little while, I need to get my test rig going, and give this whole area a poke... Meanwhile, if you want to use this, just adjust your 'auth methods' line to use samstrict_dc... Andrew Bartlett (This used to be commit 18e598ec24493026008fcfe486057555b8832108)
