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 Error Traceback: View as: Interactive | Text | XML (full) AttributeError: 'NoneType' object has no attribute 'user' URL: http://xxx.xxx.xxx/dataset/list?sort=-update_time&f-name=All&f-tags=All&f-deleted=False Module weberror.evalexception.middleware:364 in respond view
