By default, the IBM
® Sametime Community Server automatically logs out users who attempt to connect from clients of versions earlier than the specified minimum. To allow users with earlier clients to continue to access the server during the transition to the new server version, you can configure the server to allow logins from client versions earlier than the specified minimum.
About this task
Maintaining a flexible login policy is especially important in environments that include a large number of older Sametime clients. In such an environment, immediately enforcing a minimum client version can result in a high volume of help desk calls. To avoid locking users out of Sametime
®, give users several weeks to upgrade and use the ST_FORCE_LOGOUT_OLD_CLIENT_VERSION setting to enable servers to continue to accept logins from earlier client versions. After the deadline for upgrading passes, change the value of the setting to block logins from clients that do not meet the minimum security level.
The ST_FORCE_LOGOUT_OLD_CLIENT_VERSION setting determines whether or not users of old clients are allowed to stay logged in to the community. By default, when this setting is true (a value of 1), old client versions are disconnected. When the setting is false (a value of 0), the users of old clients remain online an usually a message is sent to them.
The VP_SECURITY_ALLOW_USER setting was renamed ST_FORCE_LOGOUT_OLD_CLIENT_VERSION in Sametime 8.5. In order to smooth migration, ST_FORCE_LOGOUT_OLD_CLIENT_VERSION overrides VP_SECURITY_ALLOW_USER from prior versions. If it is not present, then its default value will be 1 and VP_SECURITY_ALLOW_USER or its own default value takes affect.
- Open the sametime.ini file in a text editor. By default the file is located in the Sametime installation folder, for example, C:\Lotus\Domino\Sametime.ini.
- In the [Config] section of the sametime.ini file, specify whether to allow logins from clients earlier than the minimum allowed version by providing one of the following values for the ST_FORCE_LOGOUT_OLD_CLIENT_VERSION setting:
Save and close the file.
- 0 - Allows logins from all clients, regardless of version.
- 1 - This default setting, rejects login attempts from clients of versions earlier than allowed by the ST_MINIMAL_CLIENT_VERSION setting.
