Fix for bug #4801: Correctly implement lsa lookup levels for lookupnames.
This patch is still incomplete in that winbindd does not walk the the trusted domains to lookup unqualified names here. Apart from that this fix should be pretty much complete. Michael (This used to be commit f7efc0eca9426e63b751c07a90265a12bb39cf95)
