Recently I started a conversation about an integration of my company's application to the ADFS of our client. Their team generated a XML (FederationMetadata.xml) and gave it to us, now they're asking for a XML that should be generated by us and imported into their ADFS. I have no idea what this XML I need to generate is. Searching on internet I haven't found anything in this way, which made me question if that is right (giving back a config xml, what configs??)
My application runs using PHP. Is there a succinct documentation I can start with and is that concept of returning a XML (to be imported in ADFS) generated using FederationMetadata.xml right?
Thank you
