Introduction
The purpose of the eduGAIN Connectivity Check 2 is to identify eduGAIN Identity Providers (IdP) that are not properly configured. In particular it checks if an IdP properly loads and consumes SAML2 metadata which contains the eduGAIN Service Providers (SP). The check results are published on the public public eduGAIN Connectivity Check 2 web page (https://technical-test.edugain.org/eccs2/). The main purpose is to increase the service overall quality and user experience of the eduGAIN interfederation service by making federation and Identity Provider operators aware of configuration problems.
The check is performed by sending a SAML authentication request to each eduGAIN IdP and then follow the various HTTP redirects. The expected result is a login form that allows users to authenticate (typically with username/password) or an error message of some form. For those Identity Providers that output an error message, it can be assumed that they don't consume eduGAIN metadata properly or that they suffer from another configuration problem. There are some cases where the check will generate false positives, therefore IdPs can be excluded from checks as is described below.
The Identity Providers are checked once per day. Therefore, the login requests should not have any significant effect on the log entries/statistics of an Identity Provider. Also, no actual login is performed because the check cannot authenticate users due to missing username and password for the IdPs. Only Identity Providers are checked but not the Service Providers.
The eduGAIN Connectivity Check 2 is configured to maintain a history of 7 days of the results collected.

Check performed on the IdPs
The check executed by the service follows these steps:
- It retrieves the eduGAIN IdPs from eduGAIN Operator Team database via a JSON interface.
For each IdP that it was not manually disabled by the eduGAIN Operations Team or by IdP administrator via "robots.txt", the check verifies the SSL certificate of the IdP, creates a Wayfless URL for each SP involved and retrieves the IdP login page.
It expects to find the HTML form with a username and password field. Therefore, no complete login will happen at the Identity Provider because the check stops at the login page.
The SPs used for the check are "SP Demo" (https://sp-demo.idem.garr.it/shibboleth) from IDEM GARR AAI and the "AAI Viewer Interfederation Test" (https://attribute-viewer.aai.switch.ch/interfederation-test/shibboleth) from SWITCHaai. These SPs might change in the future if needed.
The SAML authentication request is not signed. Therefore, authentication request for any eduGAIN SP could be created because the SP's private key is not needed.- In the end, the check is run again for those IdPs that have not been checked due to a problem met with the headless webdriver and signals if there are problems on the log file.
Statuses and results
The tool uses the following statuses for IdPs:
...
- IdP does not support HTTP or HTTPS with at least SSLv3 or TLS1 or newer (these IdPs are insecure anyway)
- IdP is part of a Hub & Spoke federation (some of them manually have to first approve eduGAIN SPs)
- IdP does not use web-based login form (e.g. HTTP Basic Authentication or X.509 login)
- IdP does not allow requests coming from the ECCS2 servers: technical-test.edugain.org / technical.edugain.org
Disable Checks
In cases where an IdP cannot be reliably checked, it is necessary to create or enrich the robots.txt file on the IdP's web root with:
User-agent: ECCS Disallow: /
