Select one or more user accounts from the list in the Security tab. To select more than one row, use
the SHIFT key to select a range of users, or use the CTRL key while selecting
individual rows.
Click Drop user in the Security tab. A dialog appears in which you must
confirm the deletion before it is committed.
Click OK. The user
account no longer appears in the Security
tab.
Note: You can view a list of users whose accounts have been
deleted (and who, therefore, do not have any active privileges) by selecting
the Show Inactive Privileges check
box.
