Interface to external authentication systems

What is the mechanism?

• The common way:
  
  • sit behind a reverse proxy
  • proxy intercepts a special request
  • after login is complete, proxy redirects to the original request.
  • HTTP header must contain a UID or equivalent identifier.
  • Commonly Apache, with a module to accomplish the work
• The other way
  • specify a redirection URL
  • No proxy or interception required.
  • HTTP header is the same.
• Where is the /loginExternalAuthReturn page?
  • VIVO just redirects from there.
    • Home page
    • Profile page
    • New account

How to debug?

• Is the request being intercepted?
  
  • Increase the log settings
  • Look at headers
  • Is your UID in a header?
  • Configure VIVO to read that header.
• Otherwise, configure the reverse proxy to intercept it.
