Can't allow public access to share

[David J. Streb]

Under samba 1.8.x we could allow access for users not added as users on the 
Unix system.  Since we upgraded to 2.0.0, only people who have been added 
as users can access our [public] share.  What do I need to do differently? 
 Sun Ultra 1 running Solaris 2.7, Samba 2.0.0
