Zoho Help SP claims no metadata

Thanks, yes, I also couldn't find a requirement per the standards docs you referenced.

Am I correct that, regardless of this SP's willingness to provide metadata, it will nonetheless be required for configuring the Shib IdP to work with them?

I'm pessimistic we'll be successful in perusading this SP to do the sane thing if they are unconvinced they are not already doing so. If that's the case, are we left with the option of creating metadata for them ourselves?

Given their mention of one of the few pieces of information they will provide being a relay state, does this imply they are expecting IdP-initiated/unsolicited SSO? This would also be a first for us.

I've found this documentation


Pardon the possibly dumb questions, but I found it a little ambiguous. Where it discusses the request interfaces for SAML 1.x/2, are those to be in the SP metadata? I'm assuming so (since it doesn't make sense to put SP specific info in the IdP's metadata), but would appreciate confirmation.

Assuming it goes in the SP metadata, are those location endpoints defined in AssertionConsumerService elements in the SPSSODescriptor? If not, where do they belong? The example SP metadata here doesn't provide an examples for unsolicited SSO that I see here:

>Has anyone set up their IdP to interoperate with the Zoho SP? When I queried about their metadata, they responded, "Please be informed that we do not have possess any specific meta data. However, we will provide login/log out URL and default relay state (Request URL/Response URL)". This lack of metadata, and expectation of its non-availability is unique in our experience. They have some documentation on configuring SAML SSO for non-Shibboleth IdPs here:
