I did the setup for a ProFTP server on my Ubuntu workstation before-hand, but when replicating it on a Ubuntu server, mod_sql_passwd is simply missing.

When I enable the module, I get the following error:

Fatal: LoadModule: error loading module 'mod_sql_passwd.c': Permission denied on line 51 of '/etc/proftpd/modules.conf'

mod_sql_passwd files (.so and .c) are simply missing, whereas on my workstation it was a simple matter of enabling the configuration.

The biggest difference with the server is that it's a release gap. I will be upgrading the server, which is at the latest LTS release, in case it's the reason why.

It does appear like there may be some differences in the versions of proftp available.

If you look at the list of files from lucid mod_sql_passwd is not present, but the file is present on oneric.

That's the conclusion I had. Upgrading the distribution caused me some other issues, but it did solve the missing sql_passwd. – StrangeElement Mar 1 '12 at 21:24
