So, implementation has gone very well, until someone asked the question "How do we know users are not sharing passwords?" There are controls in place to force regular changing of password, but of course they could be shared too. Is there a way for pam to log (anywhere) the source IP addresses?
I've looked at pages for pam_debug.so but I can't understand it.
What I see in /var/log/secure is something like this:-
So I get a nice message that I'm allowed through and donald.trump is not. What would be nice is something more like sshd kicks out:-
Is there a way to turn this sort of thing on? There is nothing useful in
/var/log/messages
/var/log/secure
/var/log/audit/audit.log
directory /var/log/ss5 is empty (and not referenced in /etc/rsyslog.conf either)
I'm sure pam is meant to be helpful, but it's very confusing.

pam_nologin
PAM_NOLOGIN(8) Linux-PAM Manual PAM_NOLOGIN(8)NAME
pam_nologin - Prevent non-root users from login
SYNOPSIS
pam_nologin.so [file=/path/nologin] [successok]
DESCRIPTION
pam_nologin is a PAM module that prevents users from logging into the system when /var/run/nologin or /etc/nologin exists. The contents of
the file are displayed to the user. The pam_nologin module has no effect on the root user's ability to log in.
OPTIONS
file=/path/nologin
Use this file instead the default /var/run/nologin or /etc/nologin.
successok
Return PAM_SUCCESS if no file exists, the default is PAM_IGNORE.
MODULE TYPES PROVIDED
The auth and acct module types are provided.
RETURN VALUES
PAM_AUTH_ERR
The user is not root and /etc/nologin exists, so the user is not permitted to log in.
PAM_BUF_ERR
Memory buffer error.
PAM_IGNORE
This is the default return value.
PAM_SUCCESS
Success: either the user is root or the nologin file does not exist.
PAM_USER_UNKNOWN
User not known to the underlying authentication module.
EXAMPLES
The suggested usage for /etc/pam.d/login is:
auth required pam_nologin.so
NOTES
In order to make this module effective, all login methods should be secured by it. It should be used as a required method listed before any
sufficient methods in order to get standard Unix nologin semantics. Note, the use of successok module argument causes the module to return
PAM_SUCCESS and as such would break such a configuration - failing sufficient modules would lead to a successful login because the nologin
module succeeded.
