Starting with mapp Services 6.6.0, the OPC UA Interface of MpAudit has to be explicitly enabled (disabled by default).

This has unfortunately been missed from the Revision Information. 😢

Once this configuration property has been set to `TRUE`, MpAudit should behave the same as in version 6.5 (or lower).
