I have Asus Wl-500gp router with Samba 2 built in the firmware (Oleg version WL500gp-1.9.2.7-10). This Samba was working well. The installation of Samba 3.6

Code:
ipkg install samba36
was without problems and smbd and nmbd are automatically started after reboot:

Code:
  151 admin      1976 S   /opt/sbin/nmbd -D
  153 admin      3600 S   /opt/sbin/smbd -D
  165 admin      3480 S   /opt/sbin/smbd -D
Here is also the log from /opt/var/samba/log.nmbd file after rebooting the router:

Code:
[2013/06/01 13:23:09,  0] nmbd/nmbd.c:861(main)

I also tried the option

Code:
security = user
to suppress the warning message but the result was the same - in Windows XP or 7 no connection to Samba share is established. The same connection which was working with Samba 2.
Here is my smb.conf file:

Code:
[global]
        workgroup = WORKGROUP
        guest account = admin
        security = share
        map to guest = Bad User
        browseable = yes
        guest ok = yes
        guest only = yes
        log level = 1
        max log size = 100
        encrypt passwords = no
        preserve case = yes
        short preserve case = yes
        dns proxy = no
        netbios name = ASUS_SAMBA
        server string = Asus WL-500W
        socket options = TCP_NODELAY IPTOS_LOWDELAY SO_KEEPALIVE SO_SNDBUF=8192
        bind interfaces only = yes
        interfaces = 192.168.1.2/24
        hosts allow = 192.168.1.2/255.255.255.0
        printcap name = /dev/null
        load printers = no
        printing = bsd

[z]
        path = /tmp/mnt/disc1_3
        writeable = yes
        browseable = yes
        force user = admin
Would you have an idea why it is not working? What can I try or check? I have no more ideas.
