Dear OpenNebula comminity users and support  
I change oneadmin password using echo ‘oneadmin:passwrd’ \> /var/lib/one/.one/one\_auth  
After that opennebula service is running but I am not able to login via sunstone and it gives me  
below message “[one.user.info] User couldn’t be authenticated, aborting call.”

anyone could help me to handle this case ?

The oneadmin user is a special one. You should follow the procedure that is written in the [documentation](https://docs.opennebula.io/6.8/management_and_operations/users_groups_management/manage_users.html#change-credentials-for-oneadmin-or-serveradmin).
