title: Jenkins Slave using JNLP requires security prompt
body: <p>We are using Jenkins to drive automated GUI test in different Virtual Machines. OS is Win7/64 and other Windows variants. The virtual machines are connecting to the Jenkins Master using the JNLP way. Switching to other connections is not possible because the Jobs must execute programs with a GUI.</p>
  
  <p>Thanks to increased security requirements Java is now issuing a dialog to confirm the execution of the Jenkins Remoting Agent. This obviously destroys the automatic execution of the tests. This dialog is presented once in 24 h. Increasing this period of time to a year would solve our problem, too.</p>
  
  <p>The provided details are mentioning different aspects, like
  Application's associated file (JNLP) does not have a digital signature</p>

  <p>We are have tried different Java versions (7u67, Java 8u11 and 8u20) and different security settings.</p>
  
  <p>Jenkins is the latest stable 1.565.1 (tried an updated and a newly installed version). A try was given latest Jenkins 1.576 in a fresh install, too.</p>
  
  <p>Is this problem solvable on our side or only on the Jenkins side?
  Any ideas to solve this problem?</p>
