Use these commands to remove a user or group. Removing a user or group withdraws the authorization permissions for all roles to which they have previously been added.
To run these commands, use the AdminTask object of the wsadmin scripting client. Each command acts on multiple objects in one operation. The commands are provided to allow you to make the most commonly-required types of update in a consistent manner, where modifying the underlying objects directly would be error-prone.
