Future feature question: mapping user name automagically

[David Collier-Brown]

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
obvious
reasons, he didn't want to create a username map manually, and was
looking
for a programmatic way of doing the equivalent.
  What he hoped to do was shift the task to the users, by telling them
to
connect to //<server>/<share> where <share> was the name of the unix
account.
Alas, there was no obvious way to do this.

  I'm speculating that one might create an "auto" username map to
achieve the
effect.
  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
map_username,
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:
this
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
mapping
to <pathname> for other calls to use.
