I am integrating Red Hat 8.x workstations and servers into my AD Domain environment. I am using Centrify as the solution for RHEL to AD integration to provide centralized password authentication. Now I am adding RSA on top of this. I have the RSA system working correctly with Centrify and RHEL. However, I no longer log in locally as root. I can log in as a domain user with my RSA passcode, open a prompt and su to root. I am not aware of any local security settings that prohibit local root login in my environment.
What steps must be taken to allow local root login?
