Constructor Details

#initialize(connection) ⇒ Authentication

Performs an authentication to the OpenStack authorization servers. Opens a new HTTP connection to the API server, sends the credentials, and looks for a successful authentication. If it succeeds, it sets the svrmgmthost, svrmgtpath, svrmgmtport, svrmgmtscheme, authtoken, and authok variables on the connection. If it fails, it raises an exception.

Should probably never be called directly.
