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.
Best,

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
