Use the mqsideleteaclentry command to delete a Configuration Manager access control list entry that you have defined.
The user ID used to invoke this command must have full control permissions for the object being changed; see ACL permissions for more information.
When z/OS commands are run through the console, they effectively run as the Configuration Manager's started-task ID. This means that the commands inherit a Full Control root ACL and you can carry out any operation.
If you submit a console command to the Configuration Manager you can change any ACL for that Configuration Manager.
