Edit /etc/passwd and add user diantokam,copy paste user nobody configuration, leave everything same as user nobody, except for user ID and group name.

# vi /etc/passwd
root:$1$nvFplbd8$l05HR0mdTHcGprNaMg8QA1:0:0:root:/root:/bin/ashdaemon:*:1:1:daemon:/var:/bin/falsenetwork:*:101:101:network:/var:/bin/falsenobody:*:65534:65534:nobody:/var:/bin/falsediantokam:*:65535:65534:diantokam:/var:/bin/false

Create password for user diantokam

# passwd diantokam

Adding diantokam to samba user

# smbpasswd -a diantokam

Enable samba service on startup

# /etc/init.d/samba enable

To start samba service

# /etc/init.d/samba start

To stop samba service

# /etc/init.d/samba stop

To accesses samba share from windows type \\samba_server_name on address bar, in my case it is \\openwrt 



or using  \\ip_address in my case, it is \\192.168.1.1



and insert username and password for diantokam that you give for smbpasswd



Done.
