Limit Concurrent Logins Individually

In selang, enter the following command:
capamsc141
In selang, enter the following command:
chusr username maxlogins(NumLogins)
The concurrent logins limit set for a user overrides the systemwide limit. To prevent 
Privileged Access Manager
from enforcing the concurrent logins limit for a specific user, set the concurrent logins limit to zero for the user. You cannot use selang if you set the maximum number of concurrent logins to one.
