MTLS
Live Communications Server also uses Mutual Transport Layer Security (MTLS) to configure a trust
between Live Communications Server servers. A server certificate is applied within the Live
Communications Server console to enable a MTLS connection from one Live Communications Server
to another with an Extended Key Usage (EKU) setting of Server Authentication. MTLS is also used to pro-
vide secure connectivity to the public Instant Messaging networks, which include Yahoo, MSN, and AOL.
