Thanks for the ideas guys, I was able to get in at least!  Seems to be a 
SELINUX issues with Spacewalk 2.6 and CentOS 7.4. Upgrading to Spacewalk 2.7 
did seem to fix most of it though PAM auth still doesn't work right so I just 
left it disabled for now.

Unfortunately you can have only certain users using pam. It's a global option.
So disable pam, (re)set local password, fix the pam issue and reenable it.
