[Users] Pxeboot - pwd/login issue

Hi Mike,
I ran into the login/pwd problem again with this new build. Kernel option adminpw worked but only for a short time. I was asked to change pwd immediately after login but then rejected again after I did that. There was an short-lived error message on the screen but I wasn't able to capture it.
I tried the latest from archipel source and it worked without password issue. I pulled it from:
git clone https://github.com/primalmotion/Archipel.git
There might be a few updates right after you pulled it last time.
Would you mind merge the new updates into ovirt node again?
Thanks.
David
