Dear Maintainer,

   * What led up to the situation?
Installing with preseed and, at first reboot, using gnome-initial-setup for a user (not an admin user) and Enterprise login.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
Click on "Set Up Enterprise Login"
Fill in the active directory domain with ad user and password
Fill in the hostname, the active directory administrator's name and password

   * What was the outcome of this action?
User account created and added in local sudo group

   * What outcome did you expect instead?
User account created.


A "workaround" is to launch following command after installation:
deluser <user.login> sudo

Must gnome-initial-setup with Enterprise login be filled with an admin account, only ?

Regards,
Fernando
