While we would like to have site behind authentication realm, there are instances when our galaxy datasets/histories need to be accessible publicly from other websites. We tried adding an exception to auth rule for /datasets path using Location directive in apache web server configuration, however galaxy server returned an error as: >>> >>> {{{ >>> Access to Galaxy is denied >>> 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. >>> }}} >>> >>> Is there any way to share public histories and datasets when galaxy is using external authentication mechanism? I have thought about setting up (fake) anonymous REMOTE_USER variable for /datasets path, but not sure whether this is correct approach. Also, would it require any galaxy code changes? Any thoughts? >> >> Hi Shantanu, >> >> That's about all you can do, or modify >> lib/galaxy/web/framework/middleware/remoteuser.py to let these >> connections through.

Also, will it offer read-only access to the galaxy interface? Does it expose any job submission, file-uploads or any other modification/execution operations using web interface? Also, can we prevent particular galaxy-user from carrying out certain actions, e.g. running jobs, file uploads etc.? Since galaxy will create 'anonymous' user account based on the REMOTE_USER variable set for unauthenticated requests, I am wondering if such locked-down mode will be possible for a particular galaxy-user.
