Microsoft ADFS does not directly consume the InCommon metadata aggregate. However, there are numerous third-party tools that can help. One such tool is the ADFSToolkit


The production public key was recently added to the MDQ metadata aggregate to address this item: https://github.com/fedtools/adfstoolkit/issues/85


ADFSToolkit uses a 'claims provider trust group' based on metadata that contains multiple entities. If you are using this method currently, you will see the path to the legacy aggregate. You would update that path to pull the metadata aggregate from MDQ. 


Add a trust group by metadata URL
PS C:\> Add-AdfsClaimsProviderTrustsGroup -MetadataUrl https://mdq.incommon.org/entities


Or download the aggregate, https://mdq.incommon.org/entities, and save it to a local file such as metadata.xml

Add a trust group by metadata file
PS C:\> Add-AdfsClaimsProviderTrustsGroup -MetadataFile "C:\metadata.xml"
