Join a computer to a domain

For Active Directory Federation Services (ADFS) to function, each computer that functions as a federation server must be joined to a domain. Federation server proxies may be joined to a domain, but this is not a requirement.
ADFS-enabled Web servers must be joined to any domain in the same forest where the resource federation server resides whenever the Web servers host a Windows NT token–based application. This is a requirement that makes it possible for the Windows NT token-based Web agent to properly retrieve group membership information from Active Directory.
You do not have to join an ADFS-enabled Web server to a domain if the Web server is hosting claims-aware applications only.
