This is an item on the published Roadmap that has been completed. With this integration, any account can set up their organization to use Shibboleth or a standard SAML SSO.
Any user with the Owner role will see an SSO section in the org settings to turn on Shibboleth and setup the required settings.
If Shibboleth is turned on, when creating a user you can then set them up as a Shibboleth User if desired.
When a Shibboleth user goes to the Pope Tech login page and enters their email address it will redirect them to the organization’s login page.
