How to Configure the Exchange Migration Wizard for an LDAP Directory

This topic describes how to configure the Exchange Migration Wizard for an LDAP directory.

Before You Begin

To successfully complete the procedures in this topic, ensure that your environment meets the following requirements:

• You have Exchange Administrator permissions.

• You have permissions to read and create organizational units and user accounts in Active Directory.

• The non-Exchange messaging system supports LDAP, and you have the required permissions to access the non-Exchange directory information.

Procedure

To configure the Exchange Migration Wizard for an LDAP directory

1. Start Windows Explorer and open the C:\Program Files\Exchsrvr\Bin directory.

2. Open the mlmigad.ini file in Notepad.

3. In the mlmigad.ini file, find the line ADSI_ObjectClass=inetOrgPerson. Edit this line to specify the object class that is used in your LDAP directory for user objects. The object class name inetOrgPerson applies to Sun One Directory Server (formerly known as Netscape LDAP Server). Other LDAP directory systems might use different class names. For example, the LDAP server for AltN MDaemon uses the object class name MDaemonUser. In this case, you must change the ADSI_ObjectClass to ADSI_ObjectClass=MDaemonUser. Consult the production documentation for your LDAP directory to determine the correct object class name.

   Note

   To export Exchange 2003 user information from Active Directory for import into the legacy messaging system, change the ADSI_ObjectClass to the following: ADSI_ObjectClass= organizationalPerson.

4. Find the line ADSI_UserID=uid. If your LDAP directory uses different information for the user ID, edit this field accordingly. In the most general case, you can use the common name attribute to specify the user ID: ADSI_UserID=cn.

5. Find the line ADSI_EmailAddress=mail. If your LDAP directory uses a different attribute name for the e-mail address, edit this field accordingly.

6. Find the line ADSI_FullName=. Specify the full name attribute or the common name attribute so that the Exchange Migration Wizard can extract a proper display name; otherwise, the Exchange Migration Wizard uses the user's e-mail address to create the display name. Change this line to ADSI_FullName=cn.

   Editing the mlmigad.ini file

   

7. Save the changes and close Notepad.
