Load AD Contacts

Synchronize address data (e.g. Outlook Global Address List (GAL)) between different Active Directory (AD) forests.
The process is as follows:
1) Export user objects of source forest using LDIFDE (a tool provided by Microsoft)
2) Use the program LoadADContacts2 to determine differences between this export and the specified OU of the target AD forest.
3) Update the OU of the target AD forest using LDIFDE using the output of LoadADContacts2
Now users in the target forest can see the users of the source forest in their Global Address List.
Notes:
- User objects of the source AD forest are imported as contact objects into a selected OU of the target AD forest.
- LoadADContacts2 does not update the AD, LDIFDE is used for updates. Therefore tracking of updates is easy.
- Only changes are loaded to the target OU.
- Various options can be selected: See usage when starting LoadADContacts2 without arguments.
- Sample .bat files are provided.
