Security: new CONNAUTH CHCKLOCL parameter

In IBM® MQ 8.0 , a new queue manager security parameter, CONNAUTH CHCKLOCL, has been introduced.

The attribute CHCKLOCL is used to turn on user ID and password checking for local connections.

When you are migrating between IBM WebSphere® MQ 7.1 and latest version, the CONNAUTH CHCKLOCL attribute on each queue manager is set to NONE, ensuring version to version continuity, but switching connection authentication off.

For a new IBM MQ 8.0 installation, the CONNAUTH CHCKLOCL attribute is set to OPTIONAL. This means that user IDs and passwords are not required, but if they are provided they must be a valid pair, or they are rejected.
