The November 2007 meeting of the Triangle Linux Users Group, sponsored by Sun Microsystems, will be held Thursday, November 8, 2007 at Red Hat. Directions can be found here. Pat Patterson from Sun Microsystems will provide us with a developer perspective on digital identity, starting from the emergence of LDAP in the 90s, through single sign-on, SAML and the Liberty Alliance protocols to recent developments such as OpenID, Cardspace and OAuth. The emphasis will be on understanding the protocols and how they are implemented in the real world, with a particular focus on deciding which (if any!) approach to select for a given project.

Pat Patterson is a federation architect at Sun Microsystems, focusing on federation, identity-enabled Web services and OpenSSO, Sun's open-source implementation of those technologies. Pat's blog centers on identity-related topics.
