[Samba] homes share

[Ufficiotecnico Acknow Srl]

Hi everybody,
i have a problem with [homes] share in samba version 4.0.3, this share 
is not accessible, and also the security tab to set permission, through 
windows client, is not active.
Other shares, like profiles, works.
I have also tried another path but the problem persists.

Test from server:
smbclient //localhost/homes -Uadministrator%password

Domain=[xxxxxxxxxxxx] OS=[Unix] Server=[Samba 4.0.3]
tree connect failed: NT_STATUS_BAD_NETWORK_NAME



Permissions on /home/private
drwxrws---   2 root     staff    4096  6 feb 12.01 private

smb.conf
[homes]
         path = /home/private
         read only = No

Thanks
