error can occur in a topology where an enterprise has federated an AD FS server with Azure Active Directory for signing in to Office 365, and further federated the AD FS server with another non-Microsoft federation server such as Shibboleth. When Mac and iOS
Office applications sign in, Azure Active Directory sends a parameter in the sign-in request to AD FS that requests forms authentication. When AD FS relays this request to the non-Microsoft federation server, it may be unable to interpret this parameter and
it may display an error to the user, even before they are asked to sign in. </span></span><br style="box-sizing: border-box; margin: 0px; padding: 0px; color: rgb(51, 51, 51); line-height: 16px; font-family: Arial, Helvetica, sans-serif; font-size: 12pt; background-color: rgb(255, 255, 255);">
