I've been fighting with the SMTP auth configuration for a couple of days and
can't seem to get all the variables right. I have the following:
/etc/pam.d/exim:
auth required pam_unix.so
#auth required pam_radius_auth.so
account required pam_unix.so
password required pam_unix.so
session required pam_unix.so
in my exim.conf:
login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = "${if pam{$1:$2}{1}{0}}"
server_set_id = $1
and when I run exim -d9 -bd:
SMTP>> 250-ihost Hello testbed [206.71.92.238]
250-SIZE
250-PIPELINING
250-AUTH LOGIN
250 HELP
SMTP<< AUTH LOGIN

Running PAM authentication for user "shaun"

SMTP>> 535 Incorrect authentication data

/usr/log/auth.log:

-> shaun for exim service
I'm really at a loss for what's going on. I have tried also making it work
off of my radius server and the radius server seems to be returning a
positive auth when I put it in verbose debug mode, but it's getting lost in
the pam. Has anyone else out there had trouble getting this to work?
