Samba shares windows

Something what I don't understand.
fvdw software has users and shares
For the shares permissions can be set for all users.
When I map a network drive in windows computer to a share, I only can do this when the share is public....
Do I have to map drives with admin-nas or the user???
When it is admin-nas, how are the rights arranged for the share......??
