Hello Jan A,
You can perform these procedures to exclude specific data from replicating to RODCs in the forest. Because the data is not replicated to any RODCs, you can be assured that the data will not be revealed to an attacker who manages to successfully compromise an RODC. In most cases, adding an attribute to the RODC FAS is completed by the developer of the application that added the attribute to the schema.
Determine and then modify the current searchFlags value of an attribute
Verify that an attribute is added to the RODC FAS
