I wrote this steps in my personal blog...(but unfortunately are in spanish) But i think you can figure out how to install JBoss SSO with some basic (language neutral) step like: 1) Check out the sources with an svn Client (apt-get install subversion (or svn)) svn co http://anonsvn.jboss.org/repos/jboss-sso/dev/trunk/ 2) edit the file ocal.properties vi local.properties change: deploy.dir=default jboss.home=/home//<jboss-4.2.2.GA> 3) then complile in <jboss-sso>/components/build/ Run: ant installSSO and in: ../jboss_federation_server/ ant deploy-exploded This are the basics... then look in my blog the next steps of configuration.. ask me in my blog if you don't understand something..
