I'm trying to install Galaxy behind an Apache proxy using mod_auth_cas for user authentication. I've got a ways in but am now stuck with galaxy not getting the REMOTE_USER. Has anyone deployed with this module?

I have use_remote_user = true on in my universe_wsgi.ini along with a valid maildomain.

Here's my apache config:

NameVirtualHost galaxy.utah.edu:80
NameVirtualHost galaxy.utah.edu:443

CASLoginURL https://go.utah.edu/cas/login
CASValidateURL https://go.utah.edu/cas/serviceValidate

CASCookiePath /var/run/mod_auth_cas/

CASIdleTimeout 1800
CASDebug On
