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:-
Code:
Mar 1 12:13:12 PRX002 ss5: pam_succeed_if(ss5:auth): 'user' resolves to 'donald.trump'
Mar 1 12:13:12 PRX002 ss5: pam_succeed_if(ss5:auth): requirement "user ingroup socksusers" not met by user "donald.trump"
Mar 1 12:13:51 PRX002 ss5: pam_succeed_if(ss5:auth): 'user' resolves to 'rbatte1'
Mar 1 12:13:51 PRX002 ss5: pam_succeed_if(ss5:auth): requirement "user ingroup socksusers" was met by user "rbatte1"
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:-
Code:
Mar 1 13:24:40 PRX002 sshd[4523]: Accepted publickey for rbatte1 from 10.13.13.13 port 46960 ssh2
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_succeed_if
PAM_SUCCEED_IF(8) Linux-PAM PAM_SUCCEED_IF(8)NAME
pam_succeed_if - test account characteristics
SYNOPSIS
pam_succeed_if.so [flag...] [condition...]
DESCRIPTION
pam_succeed_if.so is designed to succeed or fail authentication based on characteristics of the account belonging to the user being
authenticated. One use is to select whether to load other modules based on this test.
The module should be given one or more conditions as module arguments, and authentication will succeed only if all of the conditions are
met.
OPTIONS
The following flags are supported:
debug
Turns on debugging messages sent to syslog.
use_uid
Evaluate conditions using the account of the user whose UID the application is running under instead of the user being authenticated.
quiet
Don't log failure or success to the system log.
quiet_fail
Don't log failure to the system log.
quiet_success
Don't log success to the system log.
audit
Log unknown users to the system log.
Conditions are three words: a field, a test, and a value to test for.
Available fields are user, uid, gid, shell, home and service:
field < number
Field has a value numerically less than number.
field <= number
Field has a value numerically less than or equal to number.
field eq number
Field has a value numerically equal to number.
field >= number
Field has a value numerically greater than or equal to number.
field > number
Field has a value numerically greater than number.
field ne number
Field has a value numerically different from number.
field = string
Field exactly matches the given string.
field != string
Field does not match the given string.
field =~ glob
Field matches the given glob.
field !~ glob
Field does not match the given glob.
field in item:item:...
Field is contained in the list of items separated by colons.
field notin item:item:...
Field is not contained in the list of items separated by colons.
user ingroup group
User is in given group.
user notingroup group
User is not in given group.
user innetgr netgroup
(user,host) is in given netgroup.
user notinnetgr group
(user,host) is not in given netgroup.
MODULE TYPES PROVIDED
All module types (account, auth, password and session) are provided.
RETURN VALUES
PAM_SUCCESS
The condition was true.
PAM_AUTH_ERR
The condition was false.
PAM_SERVICE_ERR
A service error occurred or the arguments can't be parsed correctly.
EXAMPLES
To emulate the behaviour of pam_wheel, except there is no fallback to group 0:
auth required pam_succeed_if.so quiet user ingroup wheel
Given that the type matches, only loads the othermodule rule if the UID is over 500. Adjust the number after default to skip several rules.
type [default=1 success=ignore] pam_succeed_if.so quiet uid > 500
type required othermodule.so arguments...
