When you add more than one account store to your Active Directory Federation Services (AD FS) configuration, account-store priority determines the order in which AD FS uses account stores. AD FS attempts to authenticate users beginning with the first account store. Only when authentication fails for a user does AD FS attempt to authenticate the user with the next account store in the priority list. AD FS tries to authenticate a user until the user is successfully authenticated or until all account stores have been tried. AD FS stops trying additional account stores as soon as one account store successfully authenticates a user.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at https://go.microsoft.com/fwlink/?LinkId=83477.

You can use the following procedure to configure the account store priority.
