can you post your settings file? What if you comment out OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT and/or the variable after?

I tried commenting out OPENSTACK_KEYSTONE_MULTIDOMAIN_SUPPORT. When that is done. The error does to next variable.

Perhaps you should check the line BEFORE that then. There is obviously a syntax error in your settings.py.

You can share the settings file in paste.openstack.org.

I remove Dashboard Horizon and reinstall again, then "chown -R www-data:www-data secret_key" in /var/lib/openstack-dashboard and allowed me to display login horizon webpage, however credential are invalid is displaying it. credential in CLI works good. I am using admin and demo user for login
