Which proftp modules does ISPConfig need?

[tom]

I've proFTP updated with the last security update. The default debian sarge installation has had brought more compiled in molules as it shows now. Now it show the following compiled in molules.
server01:~# proftpd -l
Compiled-in modules:
mod_core.c
mod_xfer.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_tls.c
mod_cap.c
server01:~#



Does ISPConfig needs any other modules?

I'm woundering about the missing proftp module "mod_auth_pam.c" because proftp seems to work but its uses pam and I can log in. I don't understand that.

I never had to install any additional proftpd module for ISPConfig, so I dont know which modules are needed. But I guess proftpd uses the /etc/passwd and shadow file directly without pam, if the pam module is not compiled in.
