401 Unauthorized error when trying to get OAuth token via AJAX

[greatbear302]

I'm getting 401 Unauthorized error too when using API in development instance (Helsinki). Under roles, rest_service role description says "Deprecated. This role is no longer required to access the REST API." When creating the user I'm using to connect, I did make sure it has "Web service access only" checkbox checked.

               $(document).ready(function () {                         
                   //get token                                               
                   var snOauthClientId = 'my_client_id';                         
                   var snOauthSecret = 'my_secret';                         
                   $.ajax({                                 
                             url: 'https://dev_instance.service-now.com/oauth_token.do?grant_type=password&client_id=' + snOauthClientId + '&client_secret=' + snOauthSecret,                                 
                             type: 'POST',                                 
                             dataType: 'jsonp',                                 
                             success: function (data) { console.log(JSON.stringify(data)); },                                 
                             beforeSend: setHeader,                                 
                             error: function () { alert('Failed!'); }//this line gets called; browser's developer tools message displays the 401 error
                   });                 
             });                   

         function setHeader(xhr) {                         
                   var snRESTUser = 'username';                         
                   var snRESTPwd = 'password';                         
                   xhr.setRequestHeader("Authorization", "Basic " + btoa(snRESTUser + ":" + snRESTPwd));                         
                   xhr.setRequestHeader('Accept', 'application/json');                         
                   xhr.setRequestHeader('Content-Type', 'application/json');                 
         }
