I figured out the answer - for suse you do not use a tradational smtpd.conf. Do not use pam in the config file - use saslauthd instead and it will work.

Subject: [suse-sles-e] Saslauthd, Pam and LDAP

Hello,

I am trying to setup secure smtp using postfix, saslauthd and ldap. I can get everything to work using the sasldb password database but once I try and use pam to access our ldap database authentication stops working.

My steps to switch saslauthd from sasldb to pam

1. changed the method in /etc/sysconfig/sasldauthd from sasldb to pam and then restarted saslauthd

2. created /etc/pam.d/smtp using

#/etc/pam.d/smtp
auth required /lib/security/pam_ldap.so
account required /lib/security/pam_ldap.so password required /lib/security/pam_ldap.so use_authtok session required /lib/security/pam_ldap.so

3. entered postfix reload

4. tried to send an email through postfix using my ldap username and password which did not work.

Error message:

May 20 09:24:39 newmail postfix/smtpd[5248]: warning: SASL authentication problem: unknown password verifier May 20 09:24:39 newmail postfix/smtpd[5248]: warning: SASL authentication failure: Password verification failed May 20 09:24:39 newmail postfix/smtpd[5248]: warning: rosco.mse.ufl.edu[10.5.46.238]: SASL PLAIN authentication failed

I did notice that the sasldauthd docs in /usr/share/doc/packages mentioned something about using saslautd.conf to interface with ldap directly. Would that be easier? Can someone point me toward some documentation regarding what I am doing that I can check or know what I am doing wrong?

Thanks in advance
