[Building Sakai] Site Unavailable using CAS login

[wendy lee]

hi, all

I configure sakai to use cas login. Sakai reports "Site Unavailable" ("The site you requested is not available.") after login with cas user "abc". I create a new sakai user whose userid is "abc". Login again but sakai still says "Site Unavailable". Why? After cas login, "Site Unavailable"'s url is http://localhost:8080/portal/sakai-login-tool/container?ticket=ST-723391-REvOoYdgQCHGjDzQd2r9WfICwM5d1Ab5yKP-20
my sakai-login-tool's web.xml are:
