Enabling CME Group Federation Single-Sign On allows users to log into CME Group applications using their own firm's credentials. It is compatible with most enterprise identity management systems. As a result, when a customer leaves his or her organization, web access to CME Group applications would be denied as soon as the user is disabled in the respective organization's directory.
