ah doh....... I just noticed this try this for jboss-federation-server.sar/conf/server.cfg.xml as configuration of federation servers on both ssosite1 and ssosite2 | <federation-server> | <partners> | <partner domain="ssosite1.com" server="http://www.ssosite1.com:8080/federate"/> | <partner domain="ssosite2.com" server="http://www.ssosite2.com:18080/federate"/> | </partners> | </federation-server> | Notice the change from ssodemo-site1 to ssosite1.com and ssodemo-site2 to ssosite2.com, The domain values should be real domain values. See if this solves the problem Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4161652#...
