W2K8 R2, AD Recycle bin and FIM


Turned on the Active Directory only to find out the FIM (Forefront Identity Manager) has not stoped synchronising some objects? Well fear not, they are in sync, but to the trash folder!

Below shows an object that is in sync, but to the delete item. There is a hotfix for it that installs on the DC. KB979214 is the patch.


Here is the KB article:

Consider the following scenario:

You enable the Active Directory Recycle Bin feature in a Windows Server 2008 R2-based domain.
You delete an object from Active Directory Domain Services (AD DS). For example, assume that you delete a user account.
You modify an object that has a relationship to the recently deleted object.
You perform an Active Directory directory synchronization (DirSync) control search to poll for the Active Directory changes in this domain.

In this scenario, the DirSync control search does not return the deactivated linked attributes from the modified object. Therefore, you cannot replicate these changes back to another database if you try to synchronize Active Directory Domain Services (AD DS) and another database.

For example, assume that you delete a user account that has the "testuser" name, and assume that this user account is a member of a group that has the "testgroup" name. Then, assume that you verify that the "testgroup" group does not include the "testuser" user account in the Active Directory Users and Computers window. In this scenario, a DirSync control search that polls for the Active Directory changes and for the request deactivated links cannot detect that the "testuser" account is joined to the "testgroup" group as an inactive member. Additionally, the "testgroup" group in another database does not include the user account "testuser" if you use the returned results from the DirSync control to synchronize Active Directory Domain Services (AD DS) and another database.

The Active Directory directory synchronization (DirSync) API functions do not identify the deactivated linked attributes correctly. This behavior causes the deactivated links not to be returned in the DirSync control search.
