No.  You're fine. :-)  No offense intended.  Sorry.

I agree completely.  That is where I was bringing up the
need for a module.  It would handle 
mapping the uid to a user for getpwuid() calls.

Don't aplogize.  No reason for it.  I'm glad to 
took the time to respond.  :-)

This is true if the the passdb and winbind modules 
could not use the same name<->uid mapping TDB.  I've not been
able to determine whether or not this is possible.  Lack 
of time so far I'm afraid. :-\

If both the passdb and winbind modules could share a single
TDB for the mapping, then you could ideally only allocate one
block of uids/gids.  However, this is not really a big deal
if you have to specify two different blocks.
