My LDAP server is working well, but at this point we're not ready to make the jump over to LDAP-only authentication. I would like to keep regular shadow passwords working for a while. I have run authconfig-tui on one of the CentOS clients and made sure "Use MD5 passwords", "Use Shadow Passwords", and "Local Authorization is Sufficient" are all checked. If I stop the LDAP server though, I'm unable to log onto this server with my ssh key or password. Is there a way to keep shadow passwords as a failover method for logging in if the LDAP server is down?
