No. Authentication happens through PolicyKit, and PolicyKit does not know about "procer3d". $ cat /etc/polkit-1/localauthority.conf.d/51-ubuntu-admin.conf [Configuration] AdminIdentities=unix-group:sudo;unix-group:admin As you can see it does know about the unix group "sudo", and accounts of the type "Administrator" belong to "sudo". So one way is to do as Jeremy suggested and change those users accounts to be "Administrator". Another way is to tell PolicyKit what you want. You can do so by creating the file /etc/polkit-1/localauthority.conf.d/52-my-admin.conf and giving it this contents: [Configuration] AdminIdentities=unix-group:sudo;unix-group:admin;unix-group:procer3d You can read more about it in "man pklocalauthority".
