Are you proposing that if winbindd finds a UID in the cache that does
not fit in the range that a new UID from the range should be assigned? 
That wouldn't be too hard to implement, but I am not sure that it is
desirable.  The side effect would be that all the files and ACLs that
were created would maintain the old uids.  When the user gets a new uid,
files that they previously created or ACLs that they were added to would
not be accessible with the new uid.

A while back I reported a bug in winbindd that caused it to crash nscd. 
While debugging this problem, I found that winbindd was horribly slow
without the caching done by nscd.  After fixing the problem so that nscd
would stay alive, name lookups became MUCH faster because repeat lookups
were being answered by nscd rather than by winbindd.

I suspect that this slowness is because winbindd talking to PDC across
the WAN rather than the local PDC.  I never really looked into it. 
Since I didn't see other people complaining about slowness, I assumed
that it was something wierd with our domain configuration.

I have seen that one too, but forget the exact circumstances.
