The question I asked seems to be a very simple one. My problem, that
certain users were not allowed to FTP into their accounts, was caused by
the fact that these people used non-standard shells: they all used
tcsh. And I did not have a file called /etc/shells listing trusted shells.

I created a /etc/shells file containing:

/bin/sh
/bin/csh
/usr/local/bin/tcsh
/usr/local/bin/bash

and everything worked fine after that.

Some people also suggested that perhaps a file called /etc/ftpusers (a
blacklist file of people who are not allowed to FTP) was causing the problem.

Thanks again for everyone's patient suggestions. I'm sorry about asking such
a ridiculously simple question.
