Hi Linux experts,<br />
<br />
<br />
My office has a linux (CentOS) email server running Sendmail &amp;&nbsp;Dovecot IMAP. &nbsp;It was configured by the IT Manager so that when a user is created on the Windows 2008 domain, the same user email account will also be available in the Linux Server.<br />
<br />
Example:<br />
- domain\john.doe user is created on AD<br />
- john.doe@linux-email.com is automatically available in the Linux Email server. &nbsp;<br />
- The login will be same as AD's (john.doe), and password is also the same as the AD's<br />
<br />
I want to learn the configuration behind it. &nbsp;However I don't know where to start to look for information. &nbsp;I was wondering if it uses the OpenLDAP, but as I followed the directions from OpenLDAP in CentOS, I don't see any configs done in those config file. &nbsp;So, I think it might not be using OpenLDAP. <br />
<br />

<br />
Can anyone suggest what could be the mechanism for this auto linkage? &nbsp;Sorry, I am a novice in Linux, hopefully I am expressing myself OK. &nbsp;Thank you.<br />
