  • 2014-11-26 17:00

     

    • Issue: Due to a problem with loading the German SAML stream, the German Identity Providers are currently unavailable in the aggregated SAML metadata and the CLARIN discovery service
    • Impact: German users cannot use their organisational login
    • Expected duration: the cause has been solved in the morning of Tursday (2014-11-27, 10:45 CET) but from then on it can take several hours before all Service Providers are again in sync
    • Note: to prevent issues like this in the future, we will work on additional local caching of the national SAML files

  • 2014-11-26 11:42: issue 2014-11-26 17:00 follow-up

    • Issue: The source of the error was an unintended change that led to a misconfiguration on CLARIN ERIC's side, which caused an expired version of the DFN-AAI SAML metadata to be loaded, and then filtered out in our SAML metadata publications. In addition, we found and resolved the issue that updates to the SVN version of the SAML metadata about SPF SPs had not been correctly synchronized since about a week.
    • Preventive measures: the risk of similar misconfigurations leading to silent loading of expired metadata or synchronization to a wrong location has been reduced. We are currently considering minimizing the validity window of the SAML metadata published by us to stimulate more frequent reloading of SPF SAML metadata by SPs. Furthermore we intend set up a system so that we are automatically notified of similar disruptions.
