samba - Oct 2013 - Shares Samba3 in Samba4

Hello,
I did the installation of Samba4 classicupgrade. Made to import the 
users and groups according to wiki.

Added another Samba4 as a member and in it put the old smb.conf to care.

See all shares on the network but can not access the shares of former 
Samba3.

Example sharing Samba3

[usuarios]
    comment              = diretorios dos usuarios
    valid users          = jose
    force create mode    = 777
    force directory mode = 777
    path                 = /home
    public               = no
    writable             = yes
    oplocks              = no

[Premium]
    comment              = Sistema Premium
    valid users          = @sist_premium
    path                 = /home/Premium
    public               = no
    writable             = yes
    oplocks              = no

[Scan]
    comment              = Arquivos Scanneados
    writable             = yes
    path                 = /home/scan
    oplocks              = no
    public               = yes
    force create mode    = 770
    force directory mode = 770
    force user           = scan


The need to do to fix this?

Thanks
