We have configured Exchange 2013 OWA and ECP to authenticate with ADFS. It is working and everything is operational. However, ADFS is getting several errors a minute that show something trying to use https://localhost/owa/ and authenticate through ADFS.
Obviously, something on or in exchange is doing this, but I have no idea what or where. Anyone have any ideas?
Here is the error in ADFS:
Encountered error during federation passive request.Additional Data
