I am going with proxmox as MTA and try to make it authenticate with our Active Directory. Going through many thread and guideline but I can not make it work with saslauthd and ldap.
Is there anyone have the exp on this?
Small write-up on how to do this in Proxmox Mail Gateway 6.x:
Once the 0: OK "Success." is received from testsaslauthd the postfix config can be done.

Small write-up on how to do this in Proxmox Mail Gateway 6.x:
- install packages for saslauthd:
Code:
apt-get install sasl2-bin libsasl2-modules - modify /etc/default/saslauthd:
Code:
START=yes
DESC="SASL Authentication Daemon"
NAME="saslauthd"
MECHANISMS="ldap"
MECH_OPTIONS=""
THREADS=5
OPTIONS="-c -m /var/run/saslauthd" - create /etc/saslauthd.conf (use a dedicated service account on ldap/ad for pmg):
Code:
ldap_use_sasl: yes
ldap_servers: ldap://10.1.1.10:389
ldap_search_base: OU=users,DC=example,DC=com
ldap_bind_dn: CN=<pmg_service_username>,OU=Service accounts,DC=example,DC=com
ldap_password: <pmg_service_password> - start the saslauthd service:
Code:
service saslauthd restart - test ldap connection through saslauthd, using a regular ldap/ad user:
Code:
testsaslauthd -u <username> -p <password> - check the logs for sasslauthd
Code:
journalctl -fu saslauthd
Once the 0: OK "Success." is received from testsaslauthd the postfix config can be done.
