Security of objects on Windows systems

Administration users must be part of both the mqm group and the administrators group on Windows systems if this ID is going to use IBM MQ administration commands.

User IDs on Windows systems

On Windows systems, if there is no message exit installed, the queue manager converts any uppercase or mixed case user identifiers into lowercase. The queue manager then inserts the user identifiers into the context part of a message, or checks their authorization. Authorizations are therefore based only on lowercase identifiers.
