Subject: [PATCH] daemon: if no local users, check if machine is enrolled in
network
GDM will show gnome initial-setup if a machine has no local users.
But it's totally possible that a machine has only remote users,
and shouldn't have a local user.
This commit detects that case, and avoids setting the HasNoUsers
property.

+
+ Use #org.freedesktop.realmd.Provider:Realms or

+
+ Realms will always implement additional interfaces, such as
+ #org.freedesktop.realmd.Kerberos. Do not assume that all realms
+ implement that kerberos interface. Use the
+ #org.freedesktop.realmd.Realm:SupportedInterfaces property to see
+ which interfaces are supported.
+
+ Different realms support various ways to configure them on the
+ system. Use the #org.freedesktop.realmd.Realm:Configured property
+ to determine if a realm is configured. If it is configured, the
+ property will be set to the interface of the mechanism that was
+ used to configure it.
+
+ To configure a realm, look in the
+ #org.freedesktop.realmd.Realm:SupportedInterfaces property for a

+ configuration, such as the
+ #org.freedesktop.realmd.KerberosMembership interface and its
+ #org.freedesktop.realmd.KerberosMembership.Join() method.
+
+ To deconfigure a realm from the current system, you can use the
+ #org.freedesktop.realmd.Realm.Deconfigure() method. In addition, some
+ of the configuration specific interfaces provide methods to
+ deconfigure a realm in a specific way, such as the
+ #org.freedesktop.realmd.KerberosMembership.Leave() method.

+
+ Use #org.freedesktop.realmd.Provider:Realms or
+ #org.freedesktop.realmd.Provider.Discover() to get access to some
+ kerberos realm objects.
+
+ Realms will always implement additional interfaces, such as
+ #org.freedesktop.realmd.Kerberos. Do not assume that all realms
+ implement that kerberos interface. Use the
+ #org.freedesktop.realmd.Realm:SupportedInterfaces property to see
+ which interfaces are supported.
+
+ Different realms support various ways to configure them on the
+ system. Use the #org.freedesktop.realmd.Realm:Configured property
+ to determine if a realm is configured. If it is configured, the
+ property will be set to the interface of the mechanism that was
+ used to configure it.
+
+ To configure a realm, look in the
+ #org.freedesktop.realmd.Realm:SupportedInterfaces property for a
+ recognized purpose-specific interface that can be used for
+ configuration, such as the
+ #org.freedesktop.realmd.KerberosMembership interface and its
+ #org.freedesktop.realmd.KerberosMembership.Join() method.
+
+ To deconfigure a realm from the current system, you can use the
+ #org.freedesktop.realmd.Realm.Deconfigure() method. In addition, some
+ of the configuration specific interfaces provide methods to
+ deconfigure a realm in a specific way, such as the
+ #org.freedesktop.realmd.KerberosMembership.Leave() method.
