With *Azure AD Kerberos*, Azure AD can issue TGTs for one or more AD domains. Windows can request a TGT from Azure AD when authenticating with Windows Hello for Business, and use the returned TGT for logon or to access traditional AD-based resources. Kerberos service tickets and authorization continue to be controlled by the on-premises Domain Controllers.
