Sort of. While the immediate motivation is for internal use, I can
imagine scenarios where mgmt apps might want to use this too. It
applies to any case where one process connecting to libvirt is doing
work on behalf of a user with different privileges.

Consider a web app running under httpd account, but authenticating
its client users. It wants libvirt APIs it invokes to have access
control checks done against the web client user's identity instead
of its own. It would be appropriate for the app to use the new
virConnectSetIdentity API call in this case.

Daniel
