Anyone had a chance to test iCM?

I am receiving the following after extending schema and installing the
NPM in iManager.

"A newer schema is needed for this functionality.
Attribute could not be found: iPrintRPMControlFlags"

Looking at the schema file packaged with iCM, I see no RPM attributes.
Schema file in SP5 seems to be the same as SP4.

NW6.5 SP4 (OES SP1), iManager 2.5

Thanks in advance,
