Computer scientist with focus on application development, especially in Java and object-oriented programming.

I like the challenge that is normally provided by heterogeneous IT environments and distributed systems. Very much preferring to do things the simplest way that is still reasonable in any given scenario.

  A webportal for mapping a federated identity onto an X.509 certificate.
  
  In today's web-centric world, federated authentication solves most of the SSO issues. However, for applications that do not use web, SAML is too complicated.
  
  Confusa aims to solve this by creating a webportal that connects the federated identity to an X.509 certifcate signed by a trusted CA. By using SAML-data to decorate the certificate, the non-SAML SPs can trust the content of the certificates.
  
  This makes it fairly easy to include non-saml services into an established federated infrastructure.
