I've been trying to get PAM authentication working for use with SMTP
auth, but I think I'm missing something. I'm running Exim 3.13 on
Redhat 6.1. In my exim.conf:
plain:
driver = plaintext
public_name = PLAIN
server_condition = "${if pam{$2:$3}{1}{0}}"
server_set_id = $2
I don't know a great deal about PAM, but I'm pretty sure I need a file
called "exim" in /etc/pam.d from what I've been able to determine. The
only thing I haven't figured out is how that file is to be configured.
The closest to success I get is:
auth required /lib/security/pam_permit.so
auth required /lib/security/pam_warn.so
auth required /lib/security/pam_pwdb.so shadow
account required /lib/security/pam_pwdb.so
Running exim with -d9, I get this output an authentication attempt:
-- Running PAM authentication for user "linuxcd" with string
"linuxcd:test"
PAM error: Authentication failure
plain authenticator:
$1 =
$2 = linuxcd
$3 = test
expanded string: 0
535 Incorrect authentication data
And /var/log/message gives me:
Feb 4 11:27:06 age PAM-warn[20121]: service: exim [on terminal:
<unknown>]
Feb 4 11:27:06 age PAM-warn[20121]: user: (uid=8) -> linuxcd [remote:
?nobody@?nowhere]
Feb 4 11:27:06 age pwdb_chkpwd[20125]: password not found
I'm not sure, but I think I'm missing something. Do I need to have the
SMTP auth use the user of the localuser attempting to authenticate? Or
is my PAM setup incorrect?
ANy help would be appreciated.
