-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi John, Seems like odd behaviour, but if that's how it works, then that'll adequately fix my problem. Thanks John/Iyad! Cheers, Eric On 06/12/2014 09:40 AM, John Chilton wrote:
Hey Eric,
I am pretty sure Iyad's configuration is right - here is a similar config for nginx with some discussion of the API problem http://production-galaxy-instances-with-cloudman-and-cloudbiolinux.readthedo.... It is fine if it is "empty" it just has to be set and in fact it should use the real remote user if available so the UI elements that target the API without a key continue to function properly (which I guess is slowly becoming all of the UI). This is what that apache config and my nginx config do I believe.
Does this answer your question, do you have lingering concerns?

Thanks for posting configs! I'm very curious how this actually works for you.
I'm running the API scripts from the galaxy server itself, and I made requests to http://fqdn/galaxy/, http://localhost:####/, and http://localhost:####/galaxy/
The request to the fqdn unsurprisingly fails as apache answers it, and apache requires authentication. Both of the localhost requests also fail (403), indicating that galaxy was forbidding me due to lack of a REMOTE_USER variable being set:
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.
- From my tests, I conclude that the routes under /api/ also have the requirement on REMOTE_USER being set. (Maybe a dev can chime in on this?) I'm fairly certain the only way to get the /api/ route to work with the apache config presented is to statically set REMOTE_USER, such that it's always a valid galaxy user. You don't set a static REMOTE_USER variable in your apache config, so when galaxy is serving requests from outside users, in my understanding, the REMOTE_USER var will be unset, and galaxy should refuse to answer it.
Cheers, Eric

Hi Eric,
It's not broken per se but the documentation is lacking on this front. You need to route your /galaxy/api folder to a proxy that does not require authentication. Maybe this isn't the best way but it works for AAFC's production galaxy. See my apache configuration file below:

https://trello.com/c/AGKePuHZ/1630-expose-use-remote-user-via-configuration-...
I don't know if this is the correct card (it's been a long day and I may be misreading it) but the API is completely broken under REMOTE_USER authentication.
running ./scripts/api/display.py {key} http://localhost:8300 returns 403 forbidden.
running ./scripts/api/display.py {key} https://fqdn/galaxy/ returns 401 Authorization Required
