Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Deploying an instant messaging gateway for external communities
Clients in a local IBM® Sametime® community can communicate with users in other communities through the Sametime Gateway.
Configuring TLS/SSL for Sametime® Gateway
Transport Layer Security (TLS) and Secure Sockets Later (SSL) provide encrypted SIP communications between Sametime® Gateway Server and the external instant messaging communities such as AOL®, Office Communications Server, and Sametime communities, but only if the other Sametime community requires SSL. TLS/SSL also provides encrypted XMPP communications for XMPP communities. The TLS/SSL protocols allow Sametime messages to communicate across a network in a way designed to prevent eavesdropping, tampering, and message forgery. Use these steps to set up SSL with a certificate signed by a Certificate Authority and exchange trusted certificates with external communities.
Setting up SSL on a cluster
These procedures describe how to set up Secure Sockets Layer (SSL) on a cluster of Sametime® Gateway Servers.
Requesting a certificate signed by a Certificate Authority for a cluster
To ensure Secure Sockets Layer (SSL) communication, servers require a personal certificate that is signed by a certificate authority (CA). You must first create a personal certificate request to obtain a certificate that is signed by a CA.

Requesting a certificate signed by a Certificate Authority for a cluster

To ensure Secure Sockets Layer (SSL) communication, servers require a personal certificate that is signed by a certificate authority (CA). You must first create a personal certificate request to obtain a certificate that is signed by a CA.

About this task

Complete one of these two procedures according to your deployment. Some external communities may require that the Sametime® Gateway certificate has a SAN entry, therefore you need to determine which option is preferable.
