Proftpd missing mod_ifsession/DSO support

[hutch]

Hi,

I'm trying to lock down FTP access but am having trouble due to modules not being installed. I need to use mod_ifsession to add user-based rules, but can't as the build of psa-proftpd (1.3.5a-ubuntu14.04.build1205150826.18) does not have mod_ifsession:

sudo /usr/sbin/proftpd -l

Compiled-in modules:
  mod_core.c
  mod_xfer.c
  mod_rlimit.c
  mod_auth_unix.c
  mod_auth_file.c
  mod_auth.c
  mod_ls.c
  mod_log.c
  mod_site.c
  mod_delay.c
  mod_facts.c
  mod_ident.c
  mod_auth_pam.c
  mod_ratio.c
  mod_readme.c
  mod_quotatab.c
  mod_quotatab_file.c
  mod_tls.c
  mod_cap.c
  mod_lang.c

I've tried to reinstall psa-proftpd, but that didn't work:

sudo apt-get install psa-proftpd --reinstall

Reading package lists... Done

Reading state information... Done
Reinstallation of psa-proftpd is not possible, it cannot be downloaded.

Is there anything I can do to allow use of mod_ifsession or at least DSO support?

Running Plesk 12.5.30 on Ubuntu 14.04.4

Thanks in advance

Why do you think that this module will appear after psa-proftpd package re-installation?
