Exchange 2013 CU1 setup problem – Install-RuleCollection error in Organization preparation step (protected until CU1 is officially out for public)

I have been upgrading my RTM Exchange 2013 to CU1.  I have 2 multirole servers in DAG. I have started to install CU1 on the node hosting only passive copies of databases. In step 1 of 18. Organization preparation from GUI setup it generated error as it can be seen in the following Picture.

install-rulecollection error

Recommended workaround from Microsoft is to delete the following object from AD configuration partition using AdsiEdit

CN=ClassificationDefinitions,CN=Rules,CN=Transport Settings,CN=<Your organization name>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<domain>i,DC=<com>

The object is also shown in the Picture

After deletion setup can be restarted. Object is then re-created and setup can continue.
