Managing Sametime clients
This section provides information on managing HCL Sametime clients.
Managing client types and logins
You can manage the manner and order of client logins to HCL® Sametime®.
Configuring the single login type
The single login type mode means that only one login per user is allowed. When a client attempts to log in to the HCL® Sametime® Community Server, the server checks to see if there are any existing logins of the same user, and disconnects them. Any client on the exclusion list is not disconnected, which is useful for users who want to run multiple clients simultaneously.

      - Configuring the preferred login list
        In Sametime 11, by default, persistent chat enables a user that is logged into multiple clients to receive instant messaging sessions across all clients concurrently. In an environment that does not support persistent chat and the single login type feature is disabled, Sametime uses a default login order to determine which client type should receive the instant messaging session. A preferred login list allows you to override the default order.

Configuring the single login type

The single login type mode means that only one login per user is allowed. When a client attempts to log in to the HCL® Sametime® Community Server, the server checks to see if there are any existing logins of the same user, and disconnects them. Any client on the exclusion list is not disconnected, which is useful for users who want to run multiple clients simultaneously.

About this task

To configure the single login function and exclude certain client types from qualifying as logins, edit the sametime.ini file.

Procedure

Open a text editor on the Sametime® Community Server.
Open the sametime.ini file located in the Sametime® Community Server installation directory. For example, the default directory in Windows™ is C:\program files\HCL\domino.
In the Config section, set the following flag to activate single client login mode:
VP_ONLY_SINGLE_LOGIN_ALLOWED=1
If the flag is set to 1 the server works in the single login allowed mode. When a new client login request is received, all the previous logins are disconnected. Only one client type connection per computer is allowed at one time (related to client types, not users).
Specify which client types are not considered logins when the server checks whether to accept or disconnect clients. Separate the client types with commas.
VPS_EXCLUDED_LOGIN_TYPES=clienttype1, clienttype2
In the following configuration, even though single client login mode is activated, logins originating from C++ clients and Unified instant messaging clients will not be disconnected if they have logged in from the Sametime® client too.
VPS_EXCLUDED_LOGIN_TYPES=1002, 1304
To access Sametime® from the HCL® Notes® Basic client, update or add these settings as indicated:
- Reset this setting VP_SECURITY_LEVEL=7000 to VP_SECURITY_LEVEL=6510
- Add this setting to the [Config] section: ST_MINIMAL_CLIENT_VERSION=6510
Save the sametime.ini file.
