I finally got around to this and all is working well.  I submitted 2 patches to remoteuser.py to assist in debugging incorrect set ups. 

Last question - When a user logs out, they get the page ""Access to Galaxy user controls is disabled".  I've set the remote_user_logout_href parameter to a different website, but they still get the "Access to Galaxy user controls is disabled". 

I see it in lib/galaxy/webapps/galaxy/controllers/user.py, but I think at that point its too late.

Yes, I have a test server I'm going to check this one.  thanks for the link, that's perfect...I'll add some debugging code in here to see what's going on.

Do you have a way to verify the "HTTP_MAIL" header is actually being passed through your proxy server?  

The problem is that Galaxy still doesn't think it's receiving the expected headers, so there isn't a good way that it can tell you more about what might be going on.  If you're able to tweak Galaxy (using a test server) and add a few logging statements the code, this would be good places to check what's going on (print the `environ` dictionary associated with that request, along with self.remote_user_header to see what Galaxy is actually trying to use):

It turns out our authentication system passes a header 'HTTP_MAIL' which contains the users email address.  In galaxy.ini, I have

use_remote_user = True
remote_user_header = HTTP_MAIL

After restarting,Galaxy still gives the same error.

Hi Ryan,

It may be that Galaxy is looking for a different remote user header than your proxy is setting.  I believe by default we look for HTTP_REMOTE_USER, but this is configurable in galaxy.ini (so, you could set yours to HTTP_USER there).  Let me know if this doesn't sort it out for you and we can dig deeper!

Hi all - I'm trying to use external user authentication with Galaxy.  The external authentication passes to Galaxy the username with the mail domain at HTTP_USER. 

In galaxy.ini, I enable:
use_remote_user = True


When I try to access Galaxy, I get the message:
Galaxy is configured to authenticate users via an external method (such as HTTP authentication in Apache), but a username was not provided by the upstream (proxy) server. This is generally due to a misconfiguration in the upstream server.

But nothing in paster.log indicating what the error is. 

How do I track this down?
