title: Shibboleth and Autologin
body: <p>I have used Shibboleth with manual login, meaning the user clicks the login link on a website which opens the external page where the Shibboleth login page is.  Once authenticated it redirects them back to the original site to a Shibboleth enabled page.  </p>
  
  <p>My question is once logged in, and they go to another site, how can I authenticate them in automatically since they already have a Shibboleth session from the first site.  Do they have to click an action like the first site which in turn will autologin them in with some implicit redirects the user doesn't see, or can I do this without the user clicking a login link without doing a check on every page load.</p>
