Samba users - upgrade

[Bob Hartung]

Hi all,
   I have a running install of Redhat 8 that is about to be upgraded. 
There is a complex Samba share with users set up my someone else and I 
am new to Samba.  I have a couple of questions.

1.  Can I copy the smbpasswd file and smb.conf file from the old set up 
to Fedora 8?

2.  Does every user with acces to the Samba share have to have an 
account on the machine proper or can this be accomplished within Samba?

Thanks,

Bob
