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 instant messaging
Instant messaging features are provided primarily by the IBM® Sametime® Community Server, which supports presence, text chats, and two-way phone calls.
Securing the Sametime® Community Server
The IBM® Sametime® server uses the Internet and intranet security features of the Domino® server on which it is installed to authenticate web browser users who access Domino databases on the server.
Configuring Sametime® Community Server to use SSL encryption
Configure IBM® Sametime® Community Server to use SSL (Secure Socket Layer) for its services; and configure HTTPS when communicating with Web clients or enable LDAPS (LDAP over SSL) with the LDAP server.
Enabling encryption between a Sametime® Community Server and the LDAP server
Configure SSL encryption between an IBM® Sametime® Community Server and an LDAP server by enabling the LDAPS protocol.
Setting up a keystore for the SSL certificate used by the LDAP server
Install the GSKit program and the IBM® IKeyMan utility so you can store a copy of the LDAP server's SSL certificate. On IBM i, Sametime® Community Server comes with the IKeyMan utility already installed, but you must install DCM software instead; the instructions are in this section.
Installing and setting up Digital Certificate Manager on IBM® i
Install and set up the DCM (Digital Certificate Manager) program on an IBM® i server hosting IBM Sametime®, and ensure that Sametime trusts the LDAP server's SSL certificate.
Installing Digital Certificate Manager
Install the DCM (Digital Certificate Manager) program on an IBM® i server that hosts IBM Sametime®.

Installing Digital Certificate Manager

Install the DCM (Digital Certificate Manager) program on an IBM® i server that hosts IBM Sametime®.

About this task

On IBM i, SSL certificates are managed using the integrated DCM program. You must install and set up DCM before you can establish SSL encryption for communications between the IBM i server's LDAP client and the deployment's LDAP server. All of the following software must be installed on the IBM i server where your Sametime server is located:

5722-SS1 Option 34, Digital Certificate Manager
5722-DG1, IBM HTTP Server
5722-AC3, Crypto Access Provider 128-bit

If you need more detailed information about setting up and using DCM in order to complete the steps in this section, see the IBM product documentation at:

After selecting the appropriate IBM i release and your preferred language, select the "Digital Certificate Manager" topic in the "Security" section.
