Hi,
how come that exim can not authenticate users using PAM?
======================
PLAIN:
driver = plaintext
server_set_id = $auth2
server_prompts = :
server_condition = ${if pam{$auth2:$auth3}{yes}{no}}
server_advertise_condition = ${if def:tls_cipher }
server_debug_print = "auth: $1 $2 $3"
======================
2969 SMTP<< AUTH PLAIN AGp2AGdsdWViaXJk
2969 PLAIN authenticator server_condition:
2969 $auth1 =
2969 $auth2 = user
2969 $auth3 = password
2969 $1 =
2969 $2 = user
2969 $3 = password
2969 auth: user password
2969 Running PAM authentication for user "user"
2969 PAM error: Authentication failure
2969 expanded string: no
2969 SMTP>> 535 Incorrect authentication data
========================
unix_chkpwd[2928]: check pass; user unknown
unix_chkpwd[2928]: password check failed for user (user)
exim: pam_unix(exim:auth): authentication failure; logname= uid=93
euid=93 tty= ruser= rhost= user=user
=========================
It works just fine on the old server but not on the new one. I have
verified that the user which is considered as unknown can log in to the
console just fine, and I tried multiple users.
I have found a bug report[1] which suggests that the authentication
fails because exim uses its own user-ID to do the authentication. Yet
the bug has probably been fixed.
