[galaxy-dev] apache external auth and proftpd

Hi galaxy users, I configured galaxy with external ldap authentification using apache proxy, so my galaxy users are automatically created in galaxy database. When I want to configure proftpd to work with galaxy as it is mentionned in galaxy wiki, authentification fails on the ftp because registered password in galaxy_user table mismatchs ldap user password encrypted in SHA1. It seems to be a randomly created password. If I manually translate the ldap password to SHA1, and modify it in galaxy_user table, ftp login works correctly. I wonder how passwords are inserted in galaxy database when users are automatically created ? Is there a way to go through this ? Thanks, Laure
