6.1.4.4 msDS-Behavior-Version: Forest Functional Level

The msDS-Behavior-Version for the forest is written on the crossRefContainer object (see section 6.1.1.2.1). Only the Domain Naming Master FSMO role owner accepts updates to this attribute.

Requirements: The value of msDS-Behavior-Version for the forest is never larger than any functional level of any domain NC in the forest.

The absence of the msDS-Behavior-Version attribute on a crossRefContainer object is equivalent to the msDS-Behavior-Version attribute on that object having the value zero.

The value msDS-Behavior-Version defines the lower limit on the version of the server operating system that can run on domain controllers within the forest. Ensuring this lower limit allows advanced features to be enabled throughout the forest.

The following values are defined.
