Courier LDAP authentication with qmail.schema

Submitted by hswong3i on Sat, 2009/07/04 - 11:43

Need to include qmail.schema into your slapd.conf, and add object class qmailUser with mail attribute to user object. phpldapadmin can assist most of this setup.

For login from external MUA, e.g. Thunderbird:

  • username: postmaster (NOTE: not postmaster@example.com, we have no virtual domain support right now)
  • password: your_password

Some code snippet for Courier LDAP authentication with qmail.schema.
/etc/courier/authldaprc:

LDAP_URI ldap://127.0.0.1
LDAP_PROTOCOL_VERSION 3
LDAP_BASEDN dc=example,dc=com
LDAP_TIMEOUT 15
LDAP_AUTHBIND 1
LDAP_MAIL uid
LDAP_HOMEDIR homeDirectory
LDAP_MAILDIR mailMessageStore
LDAP_DEFAULTDELIVERY defaultDelivery
LDAP_MAILDIRQUOTA mailQuotaSize
LDAP_FULLNAME cn
LDAP_CRYPTPW userPassword
LDAP_UID uidNumber
LDAP_GID gidNumber
LDAP_DEREF never
LDAP_TLS 0

P.S. Courier LDAP authenticate seems support mailmap with extra lookup and attributes. I will need to study more if virtual domain support is required.
