It seems that you are having problem with connection between dovecot and ldap. Does your ldap server log anything? What about firewall configuration in both?

Hello, I am currently trying to setup dovecot with a director instance and have managed to configure to invocations of dovecot on my server but my dovecot log keeps giving me errors about authentication. A little background on my config I am running dovecot with postfix and using an LDAP directory. Here are the errors I am seeing in my logs.
