Hi All,

Spec: Centos 6.3x64 Dovecot-2.0.9-5.el6.x86_64

Goal:

1. Inbound emails are delivered by Dovecot and the UID/GID is determined by a local /etc/dovecot/users file.

2. I'd like to have IMAPS clients authenticate with Dovecot via LDAP.

Questions:

1. I've attempted to ensure that Dovecot will always use the local password file for mail delivery as no actual password is needed. Then the LDAP server for when the IMAPS email client connects. This appears to be working as I expect, can anyone confirm/deny the below settings are correct?

2. Is there a Dovecot architecture diagram/documentation anywhere?

Settings:

File: dovecot.conf protocols = imap lmtp listen = *

File: 10-auth.conf disable_plaintext_auth = yes auth_username_format = %Ln auth_mechanisms = plain !include auth-passwdfile.conf.ext !include auth-ldap.conf.ext

File: auth-passwdfile.conf.ext mail_location = maildir:/home/%n/Maildir #passdb {

driver = passwd-file

args = username_format=%n /etc/dovecot/users

#} userdb { driver = passwd-file args = username_format=%n /etc/dovecot/users }

File: dovecot-ldap.conf.ext hosts = sysvm-ipa.noboost.org tls = yes tls_ca_cert_dir = /etc/openldap/certs auth_bind = yes auth_bind_userdn = uid=%u,cn=users,cn=accounts,dc=noboost,dc=org base = cn=users,cn=accounts,dc=noboost,dc=org pass_attrs = uid=user pass_filter = (&(objectClass=posixAccount)(uid=%u))

File: /etc/dovecot/users craig:x:890:432:Craig:/home/craig:/bin/bash
