Is it true that with IWA direct, client requests must be directed to the DNS name for the ProxySG's Active Directory machine account?

With Integrated Windows Authentication (IWA) direct, it is indeed essential for client requests to be directed to the DNS name associated with the ProxySG's Active Directory machine account. This is because IWA relies on Active Directory to authenticate users seamlessly. By directing requests to this specific DNS name, the system can ensure that the authentication process occurs correctly, allowing users to be validated against Active Directory.

This setup is crucial for proper functionality since it utilizes Kerberos authentication methods, which require the correct DNS resolution to establish secure connections. Any deviation from this established protocol can lead to authentication failures or other issues, emphasizing the importance of sending requests to the designated DNS name.

In contrast, the other options may suggest alternative conditions or scenarios that could lead to different outcomes, but they do not align with the standard operation of IWA direct where the requirement to utilize the DNS name is fundamental.
