A list of Windows server roles. e.g., ADFS, Certificate services. Pick ADFS and research about their use cases, integration with AD DS.

Uses Case Scenarios of ADFS 

?Single Sign-On(SSO). Users who want to access apps on multiple networks or organizations can use ADFS to enable Single Sign-On (SSO) authorization. It allows users to access Internet-facing applications or services with a single sign-on (SSO) process.

?Identity Federation. Federated Identification is the concept of centralizing a user's identity. This simplifies identity management.

Identity management is carried out in order to maintain security while keeping the costs of handling user IDs to a minimum.

ADFS integration to AD DS 

?Instead of performing a separate LDAP connection to Active Directory, AD DS issued claims can be utilized with AD FS to retrieve both user and device claims straight from the user's authentication context.

?For Username/Password or Certificate Authentication, AD FS connects to AD DS as a "standard" active directory supplicant. This means it authenticates clients and retrieves user information using a variety of protocols.

?AD DS is a component of ADFS. The Active Directory stores the Identity Information that will be used by ADFS.

?ADFS also allows users to access AD-integrated programs using a web interface while working remotely, using their usual organizational AD credentials.
