How do I set a Custom Attribute for use with an ADC CA LDAP filter?

Exchange Migrator 2.x


In order to successfully use the ADC CA LDAP filter specified in NETIQKB4448, and prevent migrated mail objects from reconnecting to the target AD object, you should populate a Custom Attribute on the object you do not want replicated and clear the msExchADCGlobalNames property of the source object.  

Exchange Migrator will clear the msExchADCGlobalNames property on the target object during the migration.

  • In the 'Specify Migration Options' wizard choose the following option: Yes, I would like to use scripts.
  • Select I will write VBscripts and check the Include IADs Pointers to objects... checkbox.
  • Place the following required scripts (based on your CAs) into the appropriate scripting event:
    • Mailbox-PreProcess Event

      sourceIADS.put "extension-Attribute-11","netiq"
      sourceIADS.put "msExchADCGlobalnames", ""

      'This next line will clear the Primary NT Account on a source mailbox.
      'This line is only required if the Primary NT Account on a source mailbox
      'is actually the target AD user object

      sourceIADS.put "Assoc-NT-Account",""
      'This line is required to actually set the defined values.


There have been some instances in which clearing the Primary NT Account was not sufficient to disconnect the 5.5 mailbox from the Active Directory user and did not remove the AD user account from the permissions of the source mailbox. In those cases, it was necessary to also remove/clear the target AD user object from the Permissions tab of the source mailbox.
