+### ``check_idp_error_urls.sh``

 Given a list of entityIDs and a metadata source, bash script ``check_idp_error_urls.sh`` probes each entity and determines which of the entityIDs correspond to SAML IdP deployments. For each such deployment, the script determines whether it has an ``errorURL`` in metadata and whether or not that URL is resolvable. For example:

+### ``probe_saml_idp.sh``

+Given a single IdP entityID, the ``probe_saml_idp.sh`` script probes all browser-facing SSO endpoints in IdP metadata.
