Technology Preview Documentation
The MetadataQueryProtocol base URL is different for the production version of this service. This documentation applies only to the Technology Preview. See elsewhere in this wiki for information on the production version of this service.
The public key and its certificate for the Technology Preview of the MDQ service may change with little notice. The production version of the public key and its certificate are long-lived and stable.
Versions 3.0 and higher of the Shibboleth IdP support the MDQ protocol. If you are not running Shibboleth IdP V3 or higher, or other software that supports the protocol., you should upgrade as soon as possible. Also note that the requiredSignedRoot property is new as of v3.2.0. Upgrading to the most recent version of the Shibboleth IdP and enabling this feature will protect your deployment against man in the middle attacks.
If you have more than one metadata provider, you will want to put the InCommon Per-Entity Metadata Distribution Service after any statically configured metadata providers. If you do not do this, Shibboleth will try to fetch your static entities from InCommon each time it is requested before falling back to your static metadata providers.
In this example, we configured a one minute minimum cache duration and one day maximum cache duration, but we did not configure any timeouts. A short minimum cache duration is recommended in order to prevent failed lookups from being cached for an extended period of time. Note that Shibboleth does not refresh at the minimum cache duration value, so it is okay to have a low minimum cache duration set. The Shibboleth IdP documentation provides more information on all of the options available with the DynamicHTTPMetadataProvider.
It is strongly recommended that you enable a metadata cache duration of at least one hour, but no longer than one day, in your Shibboleth IdP.
You will need to get the new signing key certificate here: Metadata signing key for the preview environment. In this case the certificate was downloaded and placed into the credentials folder of the IdP and named incommon-mdq.pem.
