One way for a user to browse a Samba share is have a UNIX account on the Samba server. This is done via the commands adduser [username] and passwd [username]

Once the user has a local account their Samba password can be initalised by:

smbpasswd -a [username]

The -a switch adds [username] to the Samba password list.
Configure the Samba share in the /etc/samba/smb.conf configuration file to allow the new user to browse the share:

[ashare] comment = A Shared Directory path = /usr/somewhere/shared valid users = mary [newuser] public = no writable = yes

Use testparm to show your updated share. Reload the smb.conf configuration file with service smb reload command.
