U4-3123 - Umbraco 7 - unable to use email address as user name

Created by Charles Zipp 13 Oct 2013, 17:37:46 Updated by Shannon Deminick 22 Oct 2013, 22:24:58

Description When I use an email address as the user name, i get this server error when attempting to log in. I was able to use email address as user name in previous versions of umbraco.

Steps to Reproduce

1. Create a user and set the user name to an email address (i.e. somebody@gmail.com)
2. Log out of the backoffice.
3. Attempt to log back into the back office using the newly created user.

If you have chrome dev tools, you will get a HTTP status code 500 on PostLogin. Below is the stack trace.

Justification If this issue is not resolved, all of our users' user names would have to be reset to something without special characters. We would likely opt to not move forward until this is resolved as it adds cost to our migration. In addition, this is a loss of functionality from earlier versions.
