Currently my organization has in it's linux configuration two accounts with a UID of 0 - Root and Root2. If we were to set a failed login attempts setting for the Root2 account, and the account were subsequently locked, would it also lock out the Root account?
My initial thought is that locking Root2 wouldn't affect Root, since while they share a UID (and there doesn't seem to be a limit to the number of users with a UID of 0) they can obviously have different passwords. Is that accurate? Or am I missing/overlooking some mechanism in the authentication process that would lock out users with a UID of 0 and not a specific username?
