[Samba] giving user rights to files

[Valéry Roché]

Thanks Adam for your answer.

As I'm using an LDAP directory to authenticate users, do I need to do 
modifications in nsswitch.conf on the PDC ? I think so, but I'm no sure.
And on other file servers, is it required too ? I read the man page, I 
will try to find more informations by some google thing ;)

and I forgot to say that I'm using ACLs too on the shares. I don't think 
the command "chown g+s" will work with ACLs : what happens if several 
groups have rights on the share ?
