title: Flask app user authetication using OneLogin
body: <p>I am working on a Flask webapp that requires user authentication.  Currently, username and passwords are stored in the database and the server side script checks the database and authenticate the user.  I am trying to change this to OneLogin authentication that this company is using.  I have no idea now how to get this task done.
  How should I approach this?  Where should I get the info?</p>
  
  <p>Thanks!!  </p>
