ADFS Device Registration cross forest

Hi all,

 

is it possible to do device registration (and claims) across a forest trust?

 

it looks to me like it isnt possible due to the limitation of the Enable-AdfsDeviceRegistration -DeviceLocation command being "a domain within the same forest"

 

is there any other way to make this work cross forest? or is this a scenario for additional ADFS farms or moving to Azure AD registration and authentication?

(tagged ADFS 2016, its actually 2012 R2)

 

Thanks 

Pete
