Every Identity Provider's metadata will contain an <IDPSSODescriptor>
element, which contains multiple pieces of information about the IdP, including:
errorURL
protocolSupportEnumeration
<Scope>
<UIInfo>
<KeyDescriptor>
<SingleSignOnService>
Note that errorURL
and protocolSupportEnumeration
are not elements in the metadata schema. they are, rather, XML attributes in the <IDPSSODescriptor>
element. See below.
