My internal domain is foo.local and external domain is foo.com. Right now I can logon as FOO\USERNAME or USERNAME@FOO.LOCAL.
If I add a new UPN suffix of foo.com and make that the default suffix for a particular user account will that user still be able to logon as username@foo.local? Even though their new default UPN is foo.com I want to make sure that foo.local will still authenticate a user successfully. Can anyone confirm this behavior? Thank you in advance.
