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.
Please contact your local Galaxy administrator.
Hi Prakash,
This was not previously possible, but I have added a config option for it:
If you're running the stable branch, you can apply the changes from this commit manually.

Hello Prakash,
I am going to move this over to the galaxy-dev@bx.psu.edu mailing list where it will have greater visibility within our development community.

Hi,
We have a SSO environment provided by Oracle Fusion products and for some reason, they don't like to send over HTTP_REMOTE_USER as a header variable to downstream servers. I have seen it before with other web sites I have integrated with Oracle Access Manager. Is there a way Galaxy can accept another HEADER variable than REMOTE_USER for its external authentication?
As an extension:
- With just enabling HTTP_REMOTE_USER as a header variable from an external authenticator, Galaxy works without any issues. I tried this with a default Apache/mod_ldap/mod_authnz_ldap setup.
- However, when I mix the Oracle gateways into the mix, things break down.
- I made OAM send HTTP_AUTH_USER over to Galaxy.
- I changed all instances of REMOTE_USER to AUTH_USER in the installed location of Galaxy in my server.
- Authentication works fine, but I get issues with HISTORY part of Galaxy (below), when I access a workflow or basically any part of Galaxy that depends on HISTORY
