Subject: [PATCH] display: ask accountservice if there are users rather than
enumerate users
At the moment we ask accountsservice to give us the list of users just
to find out if there is a list of users.
That's rather inefficient and might be wrong for directory server users
that have never logged in before.
This commit changes gdm to ask accountsservice the question we really
want to know the answer to; whether or not there are users.
