Azure AD Connect and federation

Azure Active Directory (Azure AD) Connect lets you configure federation with on-premises Active Directory Federation Services (AD FS) and Azure AD. With federation sign-in, you can enable users to sign in to Azure AD-based services with their on-premises passwords--and, while on the corporate network, without having to enter their passwords again. By using the federation option with AD FS, you can deploy a new installation of AD FS, or you can specify an existing installation in a Windows Server 2012 R2 farm.
