Nice post about setting up SSO against a LTPA domain without using a WebSphere Application Server or Lotus Domino.

This might become handy.

Until quite recently this feature was hidden in the WebSphere Application server.
You can reach all Subject attributes using ${SubjectXX} where XX is a an specfic attribute such as ${SubjectSERIALNUMBER} or ${SubjectCN}. I think this functionality is available from WebSphere Application Server 5.1.
