samba - Jul 2006 - Socket adddress option not working in Samba 3.0.22?

Hi,
 
I am using  samba on our server with two ethernet interfaces.
One interface - 10.0.1.1 is for our internal network and the next -
192.168.1.100 is for the internet.
 
I want the samba to listen only on the first interface. I tried to use the
socket adddress option in the smb.conf file but
it does not work. Samba is listening on both interaces.
 
Have you got any ideas what I am doing bad ?
 
Smb.conf file:
 
        workgroup = TEST
        netbios name = MYSERVER
        server string = Samba NT/PDC %v
        wins support = yes
        dns proxy = yes
        name resolve order = wins hosts bcast
        time server = yes
        load printers = no
 
        encrypt passwords = yes
        security = user
        hosts allow = 10.0.1. 127.
        smb ports = 139
        interfaces = 10.0.1.0/25, 127.0.0.1
        socket address = 10.0.1.1
        bind interfaces only = Yes
        client NTLMv2 auth = Yes
        client lanman auth = No
        client plaintext auth = No

        domain master = yes
        domain logons = yes
        os level = 65
        local master = yes
        preferred master = yes
        passdb backend = tdbsam:/etc/samba/passdb.tdb
        admin users = root
        add machine script = /usr/sbin/useradd -c "Machine account" -d
/dev/null  -g 900 -s /bin/false %u
        username map = /etc/samba/smbusers
        winbind use default domain = Yes

        logon path =  <file://%25L/profiles/%25U> \\%L\profiles\%U
        logon script = logon.bat
        logon home =  <file://%25L/%25U/.profiles> \\%L\%U\.profiles
        logon drive = X:
        idmap uid = 16777216-33554431
        idmap gid = 16777216-33554431
 
 
Linux system is Fedora 4, Samba version is 3.0.22
 
Thanks!
