First: How is your directory set up?

Do you have exim delivering messages?

    Part 1. Directory Structure for Email server with Virtual Domains.
    Part 2. Exim Configuration for Delivering Email to Virtual
            Domains Using an LDAP back end.
    Part 3. Courier Configuration, Webmail
    Part 4. Server Side Filtering with Preferences in LDAP.
    Part 5. Administration tools for managing virtual domains.

(I don't have part 4 complete yet. Haven't really gotten past cli
tools for part 5 yet -- but I have a good idea for an Emacs LDAP admin
interface.)

So, I assume you have delivery working, right? For LDAP, Courier
really needs authdaemon. For the record, I'm using Debian's 0.39.1-1
package for this.

Relevent line from authdaemonrc is

    authmodulelist="authldap"

authldaprc has this:

    LDAP_SERVER = name
    LDAP_PORT = 389
    LDAP_BASEDN = o=top # You almost certainly need to change this
    LDAP_AUTHBIND = 1 # So it authenticates by binding as the user
    LDAP_MAIL = mail
    LDAP_DOMAIN = everybody.org # Change this
    LDAP_HOMEDIR = homeDirectory
    LDAP_MAILDIR = mailMessageStore
    LDAP_UID = uidNumber
    LDAP_GID = gidNumber
    LDAP_TLS = 1

Note, that for this to work, you have to have anonymous browsing
enabled at least for the mail attribute. That is,

    $ ldapsearch -x mail=test@example.com dn

should return the dn of the object containing the
mail=test@example.com. Authldap will use the dn to rebind with the dn
and password. Of course, this means that you have to have simple
(non-SASL) authentication enabled as well. (That's why I use TLS
there.)

Let me know how I can help,

Mark.
