Update UserController.cs

[MarkSPowell]

Chaning CreateNewUser to use the samAccountName instead of the email address for the LoginId of a new user. This matches what the LoginController uses to look up a user. Previously, this would only work if a users samAccountName matched their email address- this is not allowed in highly regulated enviroments, as it discloses users samAccountName.

This commit fixes #14

Tried your edit, if an admin creates an account trough /#/User the admin's username(who created the account) is inserted into the DB column LoginID.
Did the below instread, it does the thing.

List userlist = GetUserFromDifferentDomain(user.User.UserName);
var logonId = userlist[0].UserName;
//var logonId = User.Identity.Name;
//var Index = logonId.Split('');
//logonId = Index[1];

Am having the same issue, how did you resolve? Just those 2 lines error.
