User lookup - email address comparison is case sensitive

[ricemery]

Should email address domain comparison be case insensitive? I have run into a problem where Redmine is setup with lowercase email domain addresses, but Azure is returning mixed case domain email addresses.

The comparison code in the plugin is case sensitive.

From redmine_oauth_controller.rb:

  user = User.joins(:email_addresses)
               .where('email_addresses.address' => email, 'email_addresses.is_default' => true)
               .first_or_initialize

I am thinking that for Azure, comparison of the email address to the Redmine address should be case insensitive.
