This solution will work for all UI users.
1. You need to access the MAA console and select 3 (command line shell) or log in via SSH using the g2 user account.
2. Get the accounts user UID:curl -s localhost/rapi/system/users?username=admin | grep users_uid
Set the password "password
" for the user and the role as administrator as our example "admin" will require this. curl -X POST -d "ui_password=password&ui_roles=administrator" localhost/rapi/system/users/<users_uid>
