ASP.NET MVC membership - wrong username casing used

When a user logs in with the default implementation of the membership service in an ASP.NET MVC project, they are logged in with a username with whatever case they used when logging in.

For example, I create a user called John. If I then log in as joHN, then User.Identity.Name will equal joHN. I would like it to equal John, the actual user's login name.

At the moment I'm getting around this like so:

var membershipUser = Membership.GetUser(model.UserName);
var membershipUserName = Membership.GetUserNameByEmail(membershipUser .Email);
FormsService.SignIn(membershipUserName, model.RememberMe);

instead of the default implementation:

FormsService.SignIn(model.UserName, model.RememberMe);

It seems a bit circuitous. Is there a better way to do this?

You could always just enforce your own case. Like if these are people's real names (even if some weird names) you could just do something like:

 TextInfo culture = new CultureInfo("en-US", false).TextInfo;
  FormsService.SignIn(culture.ToTitleCase(model.UserName), model.RememberMe);

And make it title case. Of course this is not 100% what you asked for, but it might be better than your current solution (as this saves a call to the database at least).

Username is case-insensitive throughout the provider stack and the principal is set with whatever value is used to authenticate.

If you need to enforce case-sensitivity, you will need to either guard all points of authentication as you describe or implement a custom principal/identity.

I strongly recommend the first and will pray for you if you choose the second. ;-)

Good luck.
