I've researched this feature extensively and need help. PAM is a difficult authentication program for me to thoroughly understand although I'm learning.
Running Debian Wheezy.
Have pam setup to trigger off an email when users login using sshd -- that works fine. No problem using this command in the /etc/pam.d/sshd file:
session optional pam_exec.so /usr/local/bin/notify.sh
However, I need it to work with vsftpd and getting it to work with sshd was just a test. However, I can't get it to work with vsftpd, the contents of /etc/pam.d/vsftpd are:
auth required pam_listfile.so item=user sense=deny file=/etc/ftpusers _onerr_=succeed
@include common-account
@include common-session
@include common-auth
session optional pam_exec.so /usr/local/bin/notify-login.sh
What am I missing here? Is pam even designed to work with vsftpd? Running the following command indicates it's hooked into vsftpd, but pam_exec.so doesn't seem to want to play nicely with vsftpd.
$ ldd /{,usr/}{bin,sbin}/* | grep -B 5 libpam | grep '^/'
