[APM] NTLM Auth on partition with route domain

Hi folks,

I am aware of the article K54401337 which explains how to configure NTLM auth to the domain controller on a non-default route domain.

Scenario:

Virtual Server in route domain %1 with an attached APM policy which authenticates to a DC on the backend in route domain %2. (RDs are stricty isolated)

The route domain RD0 cannot be used for this tenant. Regarding the article the machine account has to configured in RD0, cause since years it is not possible to work with RDs on machine accounts.

My question to this is: Does f5 provide a solution without using RD0 and to configure RD0 as a child domain?

The goal is to authenticate OutlookAnywhere for a tenant xy.... Does any other solution exist to authenticate OutlookAnywhere clients within a parition which are using RDs and cannot use RD0?

Thank you & kind regards
