r23048: Simo is correct in that winbind_lookup{sid,name}_async() needs
to be able to handle SIDs in the S-1-22-{1,2} domain in order
for winbindd_sid_to_uid(), et. al. to succeed.  For 3.0.25a,
we will short circuit in the sid_to_uid() family of functions
so that smbd is ok.

For 3.0.26, we need to allow winbindd to handle all types of SIDs.
