Postfix and Active Directory Integration

Jenish_uk · 03-10-2011, 04:13 AM

Hello there,

I am trying out few stuff with Linux and Windows. I have a 'Postfix' mail server on CentOS 5.5 with 'dovecot' and 'squirrel' (webmail) working fine. I am just wondering, how can I create bulk mailboxes on CentOS 5.5 (for postscript) so that the the users can access their mail from the browser (squirrel mail)?

How can I integrate with Active Directory? I am also looking for techniques to automatically create bulk users (for example 100 users) on Active Directory with a default passwords (or random passwords if possible) that integrate with Postfix.

Would appreciate you help. Many thanks in advance.

Postfix will support virtual mailboxes using a SQL database for the account information. This will decouple you from having to use Linux accounts for each mail user. I understand that Postfix will accept LDAP authentication. I have never tried it as it goes way beyond my requirements. The book, Postfix the Definitive Guide would be a good resource, as might the Postfix documentation. There are also lots of how-to documents that will show you how to implement the virtual users.

Postfix can use virtual users. These users are stored in a database such as LDAP or MySQL. They are virtual because they do not have actual accounts on the Linux box.

The directory services in Active Directory (AD) are based on the LDAP protocol. Postfix supports the use of LDAP.

I have never tried this. It would be best to post this aspect on a Windows Server mailing list.

Most people who integrate Postfix with AD are running a Windows LAN and need a mail server for the LAN. That does not appear to be your configuration. If you need to create large numbers of virtual accounts using a script or import, I would recommend using OpenLDAP or MySQL.

I have managed to connect to the Active Directory through CentOS 5.5 but running this command '#postmap -q -v bugsbunny@acme.local ldap:/etc/postfix/ldap-users.cf' but it wouldn't find any users from AD. I have followed the instruction from this website. http://www.linuxmail.info/postfix-do...ldap-centos-5/
What's the difference between Postfix Active Directory/LDAP Integration and Dovecot Active Directory/LDAP Integration can I use either?

Many thanks,
