doPost

protected void doPost(javax.servlet.http.HttpServletRequest req,
                      javax.servlet.http.HttpServletResponse resp)
               throws javax.servlet.ServletException,
                      IOException

 Returning from the external authorization server. If we were successful,
 the header will contain the name of the user who just logged in.
 
 Deal with these possibilities: 
 - The header name was not configured in runtime.properties. Complain.
 - No username: the login failed. Complain 
 - User corresponds to a User acocunt. Record the login. 
 - User corresponds to an Individual (self-editor). 
 - User is not recognized.
 
 On entry, we expect to find:
 - A LoginProcessBean, which will give us the afterLoginUrl if the login
      succeeds.
 - A referrer URL, to which we will redirect if the login fails.
      TODO: is this equal to LoginProcessBean.getLoginPageUrl()?
 These are removed on exit.
