[galaxy-dev] user names with authentication

Hello, I have a galaxy instance authentication using LDAP. The authentication works fine, and I would like to enable the user upload option. I would like to have: user_library_import_dir = /a/path and for galaxy to look for users with just the username. So if I log in with auser@example.com I want for galaxy to look in /a/path/auser instead of /a/path/auser@example.com Is there anywhere I can set this? Best, Jillian
