I found some solution which solve only part of my problem and is not 
very "clean".

When I run winbind with these options client which are member of my 
NT4DOMAIN are now able to mout smb shares from NT4MEMBER server:

# winbindd -i -d 3 -S -n --option="netbios name"=NT4DOMAIN 
--option="ntlm auth"=yes

option "netbios name"=NT4DOMAIN overwrites this option from smb.conf: 
"netbios name"=NT4MEMBER

Nenertheless I am not able to mount smb shares from clients which are 
not members of NT4DOMAIN.
