The GUID of the peer performing the role of server when authenticating.
If you are constructing a #GDBusConnection and pass gio.types.DBusConnectionFlags.AuthenticationServer in the #GDBusConnection:flags property then you **must** also set this property to a valid guid.
If you are constructing a #GDBusConnection and pass gio.types.DBusConnectionFlags.AuthenticationClient in the #GDBusConnection:flags property you will be able to read the GUID of the other peer here after the connection has been successfully initialized.
Note that the D-Bus specification
uses the term ‘UUID’ to refer to this, whereas GLib consistently uses the term ‘GUID’ for historical reasons.
Despite its name, the format of #GDBusConnection:guid does not follow RFC 4122 or the Microsoft GUID format.
