I want ask one question. When I installed LMS for the first time, I used username : admin. Can I change the name username : admin?
The admin username (used to log in to the system) cannot be changed. However, you can change the System Identity User. The System Identity User defaults to admin, but it can be changed to any user who has full access to tasks in all LMS applications. If you have created such a user (either locally or in ACS), go to Common Services > Server > Security > System Identity Setup, and specify the new user there.
