I'm having some difficulty with external user authentication as described here - https://wiki.galaxyproject.org/Admin/Config/ExternalUserDatbases I've added these two lines to universe_wsgi.ini use_remote_user = True remote_user_maildomain = fsu.edu I've setup ldap authentication in Apache and verified I have a value in REMOTE_USER with a simple php script... RequestHeader set REMOTE_USER %{AUTHENTICATE_uid}e This adds - REMOTE_USER: dcshrum When I add in the rewrites and forward to galaxy on port 8080 I'm still getting: 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..... Any help debugging this would be greatly appreciated. I'm running out of places to look! --Donny FSU Research Computing Center
