Is it possible to configure ADFS and SharePoint to allow the ability to log on using the email address attribute from AD? This would be different that the UPN because the username and domain are different from the email user name and domian.
For example my UPN might be:
hornw@domain.com
and my email address is:
wes.horn@otherdomain.com
We want users to be able to logon using the email address to make it simple since we are using the email claim once they get into SharePoint.
Thanks.
