Looking for other third-party SPs that fail with stricter SameSite settings

[shibboleth655 at lewenberg.com]

We are testing our Shibboleth IdP against the important SPs using the 
stricter SameSite settings that will be used in the upcoming Chrome 80 
release (see https://www.chromium.org/updates/same-site).

We have found that the following SPs _fail_, that is, we cannot login at 
all:

- ServiceNow
- Instructure
- Rimeto

If you have found other third-party SPs that don't work with these new 
settings please reply to this post and let us know.

Thanks, Adam Lewenberg
