<div><p>You may want to restrict users with authority to change security
|
|
and control objects to certain workstations.</p>
|
|
<p>This prevents these users from signing on to workstations in remote locations
|
|
without your knowledge. The limit security officer system value controls whether
|
|
a user with all-object (*ALLOBJ) or service (*SERVICE) special authority can
|
|
sign on to any workstation. Limiting powerful user profiles to certain well-controlled
|
|
workstations provides security protection. This system value restricts the
|
|
security officer, users with authority over all the objects on the system,
|
|
and service personnel to the console. To give these users access to other
|
|
devices, you can use the (GRTOBJAUT) command.</p>
|
|
<p>See <a href="#qlmtsecofr__quickref">Quick reference</a> table
|
|
for an overview of the limit security officer system value.</p>
