How to disable SSH root login on overcloud node?
Issue
- By default since RHOSP7, you can't log in as root user on RHOSP.
- But in /etc/ssh/sshd_config there is no line about PermitRootLogin no. So you can't log in as root but root login is not disabled.
- There is no documentation about how to add PermitRootLogin no in /etc/ssh/sshd_config
