If your deployment includes identity synchronization with Microsoft Active Directory, an available port is required for the Message Queue instance. This port must be available on each Directory Server instance that participates in the synchronization. The default non-secure port for Message Queue is 80, and the default secure port is 443.
You must also make additional installation decisions and configuration decisions when planning your deployment. For details on installing and configuring Identity Synchronization for Windows, see Sun Java System Identity Synchronization for Windows 6.0 Installation and Configuration Guide.
