Dovecot version: 2.2.22 (fe789d2) Ubuntu version: 16.04 OpenLDAP version: openldap-2.4.42+dfsg

Configurations

# 2.2.22 (fe789d2): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.13 (7b14904) # OS: Linux 4.10.0-28-generic x86_64 Ubuntu 16.04.3 LTS disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_location = maildir:~/Maildir namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } protocols = pop3 imap service auth { unix_listener /var/spool/postfix/private/auth { mode = 0666 } } ssl = no userdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap }

I am having "Authentication failed" problem with dovecot-ldap. Before it, I had binding error and I fixed it. Now I am having authentication problem when I am trying to log dovecot (usign telnet localhost 110) using a user which is created in ldap server. I can provide any configuration file and I did this configurations according to this "https://help.ubuntu.com/community/DovecotLDAP". Now I am having an authentication error.

Thank you
