pam support for ftp.



Hi there.

I've recently wrote a pam module to use  a challenge response type
authentication in linux. It worked well with telnet, rlogin and even
dtlogin. To my dismay ftp didn't work at all.  On closer inspection it turned
out that ftp didn't support pam well at all. 

I would like to upgrade ftp's pam
support. It didn't seem to be impossible. In fact, it seemed that the code just
needed to be reorganized and slightly augmented. However the following comment
makes  me feel a little uneasy.   

/* Now use PAM to do authentication.  For now, we won't worry about
     * session logging, only authentication.  Bail out if there are any
     * errors.  Since this is a limited protocol, and an even more limited
     * function within a server speaking this protocol, we can't be as
     * verbose as would otherwise make sense.
     */

Is it possible that someone can throw a little more light on the problem of
making ftp fully pam aware.
