XADM: X.400 Addresses Are Not Resolved Correctly After You Use Ldifde.exe to Import Them to Active Directory

After you use the Ldifde.exe utility to export a contact with an X.400 address, the address may not resolve correctly when you import it to Active Directory.

This issue may occur if the X.400 address is modified to use incorrect syntax before you import the address to Active Directory. For example, this may occur if you:

1. Export a contact with a working X.400 address such as X400:c=US;a= ;p=Organization;o=SITE;s=last_name;g=first_name.
2. Modify the contact to use incorrect syntax such as X400:c=US;a= ;p=Organization;s=last_name;g=first_name; o=SITE.
3. Import the contact.

Note In this example, the correct syntax is where the organization (o=SITE) appears before the last name (s=last_name) and first name (g=first_name) of the user.

To resolve this issue, make sure that X.400 addresses use the correct syntax before you use the Ldifde.exe utility to import them.
