====== Ubuntu- PAM- Find all programs that use PAM ======

Applications have to be written with PAM library support.

To get a list of the applications on your system that can use PAM in some way, type:

<code bash>
ldd /{,usr/}{bin,sbin}/* | grep -B 5 libpam | grep '^/'
</code>

returns:

<code bash>
/bin/login:
/bin/su:
/sbin/mkhomedir_helper:
/sbin/pam_tally2:
/usr/bin/chfn:
/usr/bin/chsh:
/usr/bin/passwd:
/usr/sbin/atd:
/usr/sbin/chpasswd:
/usr/sbin/cron:
/usr/sbin/newusers:
/usr/sbin/sshd:
</code>

----

===== Check a specific application for PAM functionality =====

<code bash>
ldd $(which prog_name) | grep libpam
</code>

If it returns anything, then it can use PAM.
