[Buildroot] root passwd asked for reset every ssh login

[daggs]

Greetings,

I've created a small image with ssh, I'm trying to ssh into the machine with root account (I've enabled root access for ssh) and I keep getting a msg that tells me the passwd has expired and that I need to replace it. after I replace it the connection is terminated and I need to reconnect.
when I do reconnect and enter the new passwd, I'm greeted with the same passwd change msg.
e.g. I cannot login as root to the machine via ssh.

any ideas how to fix this?

Thanks,
Dagg.
