Identity Provider Name field

Our Service Partner is requesting that we change the value of the Name field in our IdP configuration to the URL of the published metadata file. Apparently whatever system they’re using needs the EntityID to be the metadata URL. Is this normal? The example solutions all just have the value be a basic URL. I wasn’t planning on publishing the metadata file at all, but apparently their system requires it.

I just want to ensure this won’t cause any problems, since the metadata is built from the configuration and would technically be a circular reference.

It’s unusual but shouldn’t cause any problems.
The EntityID is should be a URI. We recommend a URL although it doesn’t necessarily have to point to a web resource.
The Name fields in our SAML configuration are treated as strings. We don’t assume they’re URLs and we don’t try retrieving information using the URL.
