The Communications Infrastructure (CCI) team discusses the format of the
User Principal Name (UPN) attribute at IU has traditionally followed the ADS
domain (username@ads.iu.edu). In
order to align the value used by Active Directory with other cloud services,
the UPN will change to @iu.edu. Thus, all UPN-based logins that
use username@ads.iu.edu
need to be changed to username@iu.edu before the change goes into effect.
