Comment 11 for bug 862662

Some more testing showed that the spinning cursor is displayed only for user sessions that don't need a password to login. That is:
 * a live session.
 * a guest session.
 * a user with a blank password.
 * a user with automatic login activated (only if one does not log out then log back in, in which case a password is required).

Moreover, if gdm is used instead of lightdm, the spinning cursor is displayed independently of the way the user logs in.

Marking lightdm as the affected package.

Any clue of a possible reason why lightdm would cause this bug ?
