[Samba] Manage ACL.

[Meli Marco]

Hi,
I'm working with samba-3.0.13-1 connect to W2k3, attr-2.4.19 and
acl-2.2.27-1.
I have the following smb.conf file settings:
[global]
        netbios name = NETBIOS_NAME
        os level = 16
        wins server = XXX.XXX.XXX.XXX
        socket options = IPTOS_LOWDELAY TCP_NODELAY SO_KEEPALIVE

        workgroup = DOMAIN
        realm = REALM.COM
        security = ADS
        password server = kdc.realm.com
        encrypt passwords = yes

        allow trusted domains = Yes
        winbind use default domain = No
        winbind separator = /
        winbind enum users = Yes
        winbind enum groups = Yes

        idmap uid = 10000-40000
        idmap gid = 10000-40000

        template shell = /bin/false
        use sendfile = Yes
        printer admin = x
        admin users = x
        log file = /var/spool/samba/log.%m
        log level = 1 auth:10 sam:10
        max log size = 50
        printcap name = cups
        disable spoolss = No
        show add printer wizard = Yes
        printing = cups
        load printers = yes
        map acl inherit = yes
        nt acl support = yes
[data]
        comment = DATA repository
        path = /data
        writeable = Yes
        create mask = 0750
        force create mode = 0030
        security mask = 0750
        force security mode = 0000
        directory mask = 07500
        force directory mode = 0000
        directory security mask = 0750
        dos filetimes = yes
        hide unreadable = Yes 

Below data share there's the following structure, I use only AD users and
groups not local accounts:

/data/ root	root	group:domain users:r-x
	/user/	root	root	group:domain users:r-x (inherited)	
		/user1	root	root	user:user1:rwx
		/user2	root	root	user:user2:rwx
		/user ...	root	root	user: ...

The finaly result is every user can only read and write in theirs directory,
but instead they can't see theirs directory.
Before I was connected to NT-server using samba-3.0.7 and all works fine,
whats different in this release?
Thanks.
Marco.
