Connecting the Sametime® Connect client to the Sametime® Community Server
The Sametime® Connect Client uses Server Communities preferences to connect to the Sametime Community Server for presence and chat features.
Choosing a method for connecting to the Sametime® Community Server
The Sametime® Connect Client uses the connection method specified in Server Communities preferences. The Global connection settings apply to all Connections unless a specific server community uses an alternate connection method as defined on its Connection tab in the Preferences window.
Connecting the client through a TLS connection
When a user starts the Sametime® Connect Client with a Direct connection using TLS preference, the client connects to the Sametime Community server using the Transport Layer Security (TLS) protocol. Use this preference for clients that must connect through a FIPS proxy server.

    - Connecting the Sametime® Connect client to the Sametime® Community Server
      The Sametime® Connect Client uses Server Communities preferences to connect to the Sametime Community Server for presence and chat features.
      - Defining the host server and port for connecting to a Sametime® Community Server
        The Sametime® Connect Client uses the Host and Server community port preferences to determine the host name and port it should use when attempting a connection to the Sametime Community Server. This section also includes optional steps for configuring client with the Sametime Mux.
      - Choosing a method for connecting to the Sametime® Community Server
        The Sametime® Connect Client uses the connection method specified in Server Communities preferences. The Global connection settings apply to all Connections unless a specific server community uses an alternate connection method as defined on its Connection tab in the Preferences window.
        Connecting the client through a direct connection over TCP/IP
        When a user starts the Sametime® Connect Client with a Direct connection preference, the client connects to the Sametime Community server using a unique Sametime protocol over TCP/IP. By default, the Community Server listens for this connection on port 1533. Use this preference when the connection does not need to occur through a proxy server, and the network does not block TCP/IP connections on the port used by the client.
        Connecting the client through a TLS connection
        When a user starts the Sametime® Connect Client with a Direct connection using TLS preference, the client connects to the Sametime Community server using the Transport Layer Security (TLS) protocol. Use this preference for clients that must connect through a FIPS proxy server.
        Connecting the client through an HTTP connection
        When a user starts the Sametime® Connect Client with the Direct connection using HTTP protocol preference, the client encases the standard Sametime protocol connection information within an HTTP request in a process known as HTTP tunneling. Use this preference in the absence of proxy servers to allow clients operating behind restrictive firewalls to connect to a Sametime Community server that is also available to Internet users.
        Connecting the client through Internet Explorer HTTP settings
        When a user starts the Sametime® Connect Client with the Use my Internet Explorer HTTP settings preference, the client examines the Internet Explorer Connection settings to determine how to connect to the HCL® Sametime Community server. If no proxy server is selected, the HTTP request goes to the Sametime Community server in a direct connection. If a proxy server is selected, the client connects through the appropriate SOCKS or HTTP proxy server.
        Connecting the client through a proxy connection
        When a user starts the Sametime® Connect Client with a Use proxy preference, the client connects to the HCL® Sametime Community server through a SOCKS, HTTP, or HTTPS proxy server.
      - Configuring alternate communities for clients
        Configuring alternate communities gives users more options for logging in from their Sametime® Connect Client and Sametime Embedded Client for Notes®. For example, you can have a default community that allows users to connect using a direct connection when they are in the office and you can add an alternate community that allows them to connect to the same community through a reverse proxy server connection from home.
    - Sametime Client Configuration Options
      There are several methods to customize the user experience for Sametime clients. This section covers Expeditor based clients that are capable of leveraging the Expeditor Managed Settings framework. These clients include the Sametime client for Windows or Mac, and the HCL Notes embedded Sametime client for Windows or Mac. This does not apply to the PWA, web or mobile clients.
  - Starting and stopping servers
    This section provides information on starting and stopping HCL Sametime 11.6 servers.
  - Managing policies
    Sametime policies allows administrators to control user access to features.
  - Configuration files
    There are a number of configuration files that a backup copy should be retained after the server configuration is complete.
  - Adding additional Sametime administrators
    Sametime Community server is installed on top of a Domino server. There are some administration and installation tasks that must be performed using the HCL Notes Client or HCL Notes Administrator client.
  - Enabling multi-tenancy
    Multi-tenancy allows multiple organizations to be part of the HCL Sametime® community. With multi-tenancy, Sametime users can chat, add users and groups to contact lists, and have awareness of users in their organization or in other organizations that are configured to be visible to them.
  - MongoDB
    This section provides information relating to administering MongoDB.
  - Disabling persistent chat and MongoDB requirements
    HCL Sametime 11.6 deploys with persistent chat enabled which requires MongoDB. It is possible to remove the MongoDB requirement if persistent chat and chat logging is disabled.
  - Managing Sametime Meetings
    This topic explains the features you can enable or disable for meetings. Currently, the settings that you can change are global settings that apply to the entire server. User policies cannot control the settings.
  - Changing user names
    When you change user or group names in the directory, the change is not reflected in HCL® Sametime Community Server databases. In order to synchronize the directory names with the names in the Community Server databases, you must run the name conversion utility.
- Uninstalling Sametime
  In the event that Sametime must be uninstalled, follow these steps to uninstall the Community, Proxy, and Meetings servers.

Connecting the client through a TLS connection

When a user starts the Sametime® Connect Client with a Direct connection using TLS preference, the client connects to the Sametime® Community server using the Transport Layer Security (TLS) protocol. Use this preference for clients that must connect through a FIPS proxy server.

Before you begin

A successful connection depends on these prerequisites.

The client's preferences for the server community must contain a valid Host server and Server community port for a TLS connection.
The server must be configured to allow TLS connections from clients, see the topic: Securing connections between Sametime Community and Sametime clients.

About this task

Follow these steps to select the Direct connection using TLS method for the client.

Procedure

From the Sametime® Connect client client, click File > Preferences.
Do one of the following:
- To select this connection method for all server communities, click Server Communities. In the "Global connection settings" section, click Direct connection using TLS and click OK.
- To select this connection method for only one server community, click Server Communities, select the server community name, and open the Connection tab. Uncheck Use global connection settings, then click Direct connection using TLS and click OK. Click OK to close the Preferences window.
