The feature of windows server that allows for agentless authentication is:

AD (Active Directory)

Explanation:

Active Directory and Active Directory Services is at the pinnacle of what is called single sign-on.

When you sit down at your computer in your job, you log in once and all of the sudden all of the network resources are either available to you or are blocked to you from that single sign-on.

Agentless authentication access to the computer is administered by AD (Active Directory) and allows for administrators to sit down and essentially at one single administrator console give users and individual computers permissions to do things on the network and do things on individual computers get access to the shared files and folders through proper authentication.
