sipXecs, starting with release 3.10, is able to automatically synchronize with Microsoft Active Directory using the LDAP protocol. Synchronization can be done one or automatically at a configurable time interval. Users created or deleted in Microsoft Active Directory are then automatically synchronized with users in sipXecs, which makes administration a lot easier. the following explains the steps you have to take to accomplish this:

First, navigate to the LDAP / AD screen found under the System tab. To setup a new LDAP / Active Directory server select the "LDAP Server" link on the right side under Quick Links. This will take you to the screen below. Enter the hostname / IP address of your Microsoft server including the administrator password.
NOTE: The User section requires your full DN information, for example: CN=Administrator,CN=Users,DC=pdc,DC=mydomain,DC=com

Next, you have to select the relevant object classes you want to extract from the Active Directory database. Select just two classes: "User" and "Person" as shown below.
NOTE: Because the attributes AD uses are different from a standard LDAP installation they won't match up, you'll have to manually configure them. Standard LDAP setups such as OpenLDAP by default use those attributes unless it's configured differently.

The next screen allows you to assemble the query for the Active Directory database using a graphical interface. The search base must be: "CN=Users, DC=example, DC=com", where the DC parameters have to represent your domain. The Filter is "proxyaddress=*". Use "cn" and "sn" as the first name and last name attributes, respectively. The email address is "userPrincipalName". The Alias, User group, and SIP password attributes will vary depending on what the admin of the Active Directory server configured.
