I would like to show you the steps to create an admin user in SAP Managemant Cockpit.
Log on to SAP managment cockpit , https://<ServerName>:<Port>/Admin/
Go to Settings –> Security Profiles –> admin (cannot be deleted)
Note: Do not create any new security profile, use the default security profile as mentioned above. i.e admin (Cannot be deleted) profile.
Once you click on admin(cannot be deleted) security profile, a new window appears.
Click New and select system Login (Admin Only) as authentication Providers as shown in below screen shot.
Click Create and another window appears as shown in below screen shot. Type the username and password. Give the Role as Administrator. Note: If the Roles section is empty then admin user will not be created.
A new admin user would be created and now login with your newly created admin user. The same username would be valid to access the Gateway management cockpit also.
