I'm trying to setup a shibboleth IDP on Tomcat for SSO and I'm having some Tomcat configuration issues. I've followed the setup instructions in the Shibboleth website (https://wiki.shibboleth.net/confluence/display/SHIB2/IdPInstall). But I'm getting a 404 error saying that the idp resource I launched doesn't exist, even though I placed the idp.war (created during the shibboleth installation) in the webapps directory of tomcat. Going to the test URL provided by the setup instructions is how I found this issue (https://idp.test.org/idp/profile/Status
where idp.test.org is the tomcat server address).
I'm using an Amazon EC2 instance running 32-bit Ubuntu 12.04 LTS, Tomcat 6 and Shibboleth IDP 2.3.8
