Chef Automate SAML with ADFS

Hello all,
I am wondering if anyone has successfully configured SAML integration with ADFS. I have had success with other components; however, when I enter the metadata url specified in the documentation : https://[yourChefAutomateDomain]/api/v0/e/[yourEnterprise]/saml/metadata
I get an error on the ADFS side to ensure it’s a valid URL to metadata.

I can browse to that location from the ADFS server and see that there is XML there.

Thanks for feedback
