Doc Text:	After upgrading to Red Hat Enterprise Linux 4, attempting to open the dashboard may fail with a '500 Internal Server Error'. This is caused by an incomplete ALLOWED_HOST setting. If this occurs, you will need to: 1. Add the fully-qualified domain name of your dashboard host to the ALLOWED_HOSTS parameter of the /etc/openstack-dashboard/local_settings file. 2. Change the owner and group of the var/lib/openstack-dashboard/.secret_key_store file to 'apache': # chown apache:apache /var/lib/openstack-dashboard/.secret_key_store	Story Points:	---

ALLOWED_HOSTS = ['horizon.example.com', 'localhost', '10.13.215.133', 'rhostest.jkdexter.usersys.redhat.com']

Thank you for the report, I think this needs some docs. I'm sure, you won't need to re-install openstack-dashboard at all.

Editing/changing the ALLOWED_HOSTS setting is nothing we can or should do during install/upgrade phase at all.

This does not need any package change, but docs.

Upgrade info is now in the Release Notes; moving there.

This bug is being assigned to ddomingo, who is now the designated docs specialist for Release Notes after 4.0.z2.
