Over a weekend myself and my CoWorker decided to create a mail system using ActiveDirectory as a backend database for authentication of usernames.

This allows us a single central database for users names/passwords.

Software Configuration:
* Windows 2003 Datacenter Server
* Debian Linux 3.0 (woody)
* Exim 3.35
* Cyrus 2.1.15
* Samba 3.0b2

to be continued...

!! Exim Configuration
We need to two entries to the exim config file (/etc/exim/exim.conf).  The director entry (active_directory_user) takes a (local) email address after alias expansion (remember, order is important) and decides whether the mailbox exists and if so, what transport should be used to deliver the mail.  The transport entry (local_delivery_cyrus) will use cyrdeliver to pass the resolved mail to the cyrus mailbox and will return an error if the mailbox doesn't exist.

! Directors Section

 active_directory_user:
  driver = aliasfile
  search_type = ldapm
  query = "user=\"cn=admin,ou=Accounts,dc=domain,dc=co,dc=nz\" pass=\"Secret12\" \
          ldap://adserver.domain.co.nz:389/dc=domain,dc=co,dc=nz?sAMAccountName?sub?(sAMAccountName=$local_part)"
  expand
  transport = local_delivery_cyrus


! Transports Section
 local_delivery_cyrus:
  driver = pipe
  command = /usr/sbin/cyrdeliver $local_part
  user = cyrus
  group = mail
  return_output
  log_output
  prefix =
  suffix =


See [LDAPNotes] for more information on LDAP Urls / Searches.

!!Notes:
* In the ldap search query, the attribute __sAMAccountName__ is the pre windows 2000 Logon name (username only), the Windows 2000 logon name is stored in __userPrincipalName__ (includes @domain.co.nz).  Their email address is stored in the __mail__ attribute (bob@domain.co.nz or bob@fred.tla) -- GerwinVanDeSteeg
