When i ran samba using inetd it listens to all interfaces, even if interfaces and bind intefaces only lines are present in smb.conf.

Steps to reproduce:

Computer has 2 interfaces:
rl0 (10.1.0.1/24) and rl1 (192.168.1.8/24)

I run samba using inetd:
/etc/inetd.conf:
...
netbios-ssn stream tcp  nowait          root    /usr/local/sbin/smbd    smbd
netbios-ns dgram udp    wait            root    /usr/local/sbin/nmbd    nmbd
swat    stream  tcp     nowait/400      root    /usr/local/sbin/swat    swat
...

/usr/local/etc/smb.conf:
...
        interfaces = rl0
        bind interfaces only = Yes
...

However it uses ip 192.168.1.8 as well:
[root@server ~]# smbclient -L 192.168.1.8 -U%
Domain=[_OP] OS=[Unix] Server=[Samba 3.0.23]

        Sharename       Type      Comment
        ---------       ----      -------
        incoming        Disk      incoming
        IPC$            IPC       IPC Service (Samba Server)
Domain=[_OP] OS=[Unix] Server=[Samba 3.0.23]

        Server               Comment
        ---------            -------
        SERVER               Samba Server

        Workgroup            Master
        ---------            -------
        _OP                  SERVER

If i stop inetd and run samba manually it works as expected:
[root@server ~]# /etc/rc.d/inetd stop
Stopping inetd.
[root@server ~]# /usr/local/etc/rc.d/samba forcestart

Also this lines appear in log.nmbd when using inetd:
