New Install - Unable to Login

I have a clean RHEL 6 install. I've run yum install katello-all and then katello-configure, but when I get to the login screen and enter the default user/password, I get taken back to the login screen. I've tried a few things now such as cpsetup and katello-reset-dbs, but same results. Nothing interesting in the catalina.out log or katello logs. Using a bogus username/password gives me the same result. So what am I missing? Can someone point me in the right direction of where to look for troubleshooting. thanks, Isaac
