Example Trusted Circle SSO Deployment Scenarios

The simplest SSO deployment scenario consists of only Messenger Express and Delegated Administrator. A more complicated scenario can be created by adding Calendar Express—on the same machine or a different machine—using the same SSO prefix so they are in the same trusted circle. This is shown in Figure 6–1.

An even more complex deployment would include Messenger Express Multiplexors and load balancers.
