Nope. Nothing obvious in any of the log files (messages, syslogd, etc.).
I stepped back the last couple of changes and then tried to apply them again, thinking I may have messed up one of these steps. I'm getting the same behavior. Console login with root is hanging. SSH connections are being refused. console login with regular user is timing out/hanging.
I'm stumped. One one hand, I don't really need LDAP authentication to the server itself. On the otherhand, if that isn't working, it suggests setting up a workstation to authenticate against it will fail too. So.... Guess I'm off to learn about PAM.
