Ive followed all the steps in https://help.ubuntu.com/community/Postfix/DovecotLDAPbut I am getting a localhost postfix/smtpd[12520]: fatal: no SASL authentication  mechanismsin my /var/log/mail.errIs there a way to find out more specific root cause?Note: I have verified saslauthd is running properly using testsaslauthd. SASLAuthd is running fine. I'm struggling in trying to get deeper logs and exact cause on the postfix-sasl side, since I assume the issue will be there.
