Hello,

I’m unable to ssh as ‘root’ onto any of my new CentOS 7 hosts. I’ve always been 
able to do so on CentOS6.x

We normally have the file ‘/root/.k5login’ listing the designated system 
admins’ principals. Once on a CentOS 7, an admin can ‘ksu’ and become root as 
we expected.

We are using puppet and Foreman to build our hosts so they are in every way we 
can think of, identical, except for the O/s version.

I’ve confirmed forward and reverse DNS and that the ‘kvno’ number matches 
what’s reported by ‘klist -k’. 

I enabled "LogLevel DEBUG” in sshd_config and restarted sshd on a CentOS7 host:
