!!! [IBM] [AIX]
To debug pam issues, [IBM] has some additional [PAM] framework debug options:
{{{
touch /etc/pam_debug
}}}

!! [Syslog Facility]
Make sure "debug" priority messages are logged somewhere from /etc/syslog.conf


!!! Old Versions of [openSSH]
NOTE:  We have seen versions of [openSSH] on [AIX] that were older than 4.x and they woudl not work with PAM. We had to perform an upgrade to the latest version (4.7) adn this required an upgrade of openSSL on the ZIX box as well.
