We upgraded proftpd on the server to 1.3.5rc3 and have the following SQL part in our configuration file based on the post of http://dev.list.galaxyproject.org/ProFTPD-integration-with-Galaxy-td4660295.html

Hallo Leon and Rob,

Thanks for working on this, when I'd looked a couple months ago I could not find an entirely-ProFTPD way to do this.  I think it may have actually come about because I asked about it on their IRC channel. ;)

This may work if you change SQLPasswordPBKDF2:

  SQLPasswordPBKDF2 SHA256 10000 24

It'd be great if ProFTPD also supported pulling those values dynamically from the database, but Galaxy's PBKDF2 code currently has them hardcoded, so they will be static anyway.
