Understanding Account Stores
Active Directory Federation Services (AD FS) uses account stores to log on users and extract security claims
for those users. You can configure multiple account stores for a single Federation Service. You can also
define their priority. The Federation Service uses Lightweight Directory Access Protocol (LDAP) to
communicate with account stores. AD FS supports thefollowing two account stores:
Active Directory Domain Services (AD DS)
Active Directory Lightweight Directory Services (ADLDS)
