From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>
Currently the server determines whether authentication of clients
is complete, by checking whether an identity is set. This patch
removes that lame hack and replaces it with an explicit method
for changing the client auth code
* daemon/remote.c: Update for new APis
* src/libvirt_private.syms, src/rpc/virnetserverclient.c,
src/rpc/virnetserverclient.h: Remove virNetServerClientGetIdentity
and virNetServerClientSetIdentity, adding a new method
virNetServerClientSetAuth.
