title: Sharepoint 2013 With IE 11 - 401 UNAUTHORIZED
body: <p>I have authentication problem when used IE to access my SharePoint site.
  When I enter the address of the site, I don't receive any prompt to enter username and password and I get the error message "401 UNAUTHORIZED".
  I have no such problem when using Firefox or Chrome.
  I searched about this problem and a solution was changing authentication type in IIS from "Windows Authentication" to "Basic Authentication". This solution worked for me, but Basic Authentication is not secure and I don't want to use it. 
  Is there any solution else to solve this problem?</p>
