Another subscriber to this list had the unenviable task of adapting to
some thousands of users, all with disparate unix and NT id's.  For
reasons, he didn't want to create a username map manually, and was
for a programmatic way of doing the equivalent.
  What he hoped to do was shift the task to the users, by telling them
connect to //<server>/<share> where <share> was the name of the unix
Alas, there was no obvious way to do this.

  I'm speculating that one might create an "auto" username map to
achieve the
  In map_username, one might see of the value of  lp_username_map() was
a distinguished string, say AUTO, and if so return the share name.

  Does this sound sane? I can see where one would do the changes to
but as it's used many places[1], I'm not sure what the side-effects of
such a
change might be.
  I also don't know the then current value of <share> is in each case:
might not be possible in all cases where map_username is called.

  A variant on this might be "username map = AUTO <pathname>", which 
attempts to look up the name in the map first, then tries to map it to
username share.  If the auto mapping succeeds, it appends this new
to <pathname> for other calls to use.
