I am not aware of Galaxy having any sort of login hook as you described --- without writing custom code. This brings up the added challenge of keeping your custom modifications current with the latest release of galaxy. Another approach, and I am not sure how feasible this is on your setup, is to create all these added services during the user creation[1] process. On our HPC cluster this is the method we implemented. All our users can use SFTP, rsync, BBCP, etc to upload to the cluster and the user moves their data to galaxy by the "FTP Trick[2]" to their "dropbox" folder that galaxy has access to. Once data is moved to the dropbox folder, users login via the galaxy web interface and select the data via the Get Data -> Upload File interface. This might be a simpler approach, create these services for each new user during their account creation. You will be forced to use the command line interface to create new users, but I believe its far simpler then using postgres notify or the other methods you described.

Hello,
Does Galaxy provide a post-login hook that could be used to trigger an operating system level action upon successful login ?
Here is the scenario and use-case where that would come in handy: * Local instance of Galaxy (Nov 2012 release) on a Linux server with a PostgreSQL DB * Upload via FTP feature is enabled * Users are authenticated via LDAP and nginx * Users should be able to securely upload files (to their sub-directory within the configured FTP upload directory)
The current method being employed to fulfill this use-case is through a modification to Š/galaxy-dist/lib/galaxy/web/framework/__init__.py file that calls a a shell script which creates an OS-level user and associated FTP upload directory. Files are uploaded by users via sFTP (SSHD configured to restrict Galaxy users to a chroot'ed directory).
Options considered: * Shell/Python script that periodically queries the "galaxy_user" table and creates an OS-level user and FTP upload directory (not yet tried; introduces delay between user creation and FTP capability unless frequency of polling is high) * ProFTPD with sFTP and LDAP modules (increased administrative overhead compared to using built-in SSHD; wasn't able to get auto directory creation to work due to TBD cause) * PostgreSQL listen-notify to call a sFTP user creation script when an insert occurs in the "galaxy_user" table (not yet tried)
Thank you.
