Re: Shibboleth login

This is getting me closer.  The Shibboleth login works now.  I
authenticated with Shibboleth and that opens the Roundup tracker.

However I get a new error immediately after logging in and when I click on
the links in the menu.  For example when I click on the "User List" menu
item, I get the following message:

127.0.0.1 - - [03/Jan/2019 14:04:22] "GET /user HTTP/1.1" 200 5658

    for data in self.result:

----------------------------------------

I suspect this has something to do with the strip() function. Any thoughts
on how to fix it?
