web services - ASP.Net MVC web application Impersonated doesn't react the same way out of the server -

-

i have developed asp.net mvc 5 web application works impersonation. i'm using impersonation because web app calling navision dynamics web services , don't want users enter credentials.

i have deployed web application on windows server 2012 r2 iis 8.5. have changed application pool .net 4.5 classic classic pipeline mode , have activated impersonation authentication.

my web application works while navigate form server internet explorer raise me “system.data.services.client.dataserviceclientexception: forbidden” error when try access computer. if stay on server , change localhost myservername in url, don't error don't receive data navision.

here system web configuration

<system.web>     <compilation targetframework="4.5.1" />     <httpruntime targetframework="4.5.1" />     <authentication mode="windows" />     <authorization>         <deny users="?" />     </authorization>     <customerrors mode="off" />     <identity impersonate="true" /> </system.web>

here way consume navision service

using system.linq; using system.net; using system.servicemodel; using system.web;  namespace mywebapplication.models {     public class matter     {         public string matter_no { get; set; }         public string matter_label { get; set; }     }      public static class matterdatacontext     {         [operationbehavior(impersonation = impersonationoption.required)]         public static ienumerable<matter> getmatters()         {             list<matter> matterlines = new list<matter>();              uri uri = new uri(configurationmanager.appsettings["navisionodatauri"]);             var nav = new navserviceref.nav(uri);             nav.credentials = credentialcache.defaultnetworkcredentials;              var resultmatterlines = m in nav.matterlist                                     select m;              foreach (var m in resultmatterlines)             {                 matter ligne = new matter();                  ligne.matter_no = m.matter_no;                 ligne.matter_label = m.matter_label;                 matterlines.add(ligne);             }              return matterlines;         }     } }

i have added peace of code index debug

<table border="1">     <tr>         <td>application code executed using</td>         <td>@system.security.principal.windowsidentity.getcurrent().name</td>     </tr>     <tr>         <td>is user authenticated</td>         <td>@user.identity.isauthenticated</td>     </tr>     <tr>         <td>authentication type, if authenticated</td>         <td>@user.identity.authenticationtype</td>     </tr>     <tr>         <td>user name, if authenticated</td>         <td>@user.identity.name</td>     </tr> </table>

and receive expecting :

application code executed using: domain\jeremy
user authenticated: true
authentication type, if authenticated: ntlm
user name, if authenticated: domain\jeremy

i can't find i'm doing wrong... can me please?

you need following : - verify installed both asp.net , windows authentication on iis - once installed , iis authentication verify enabled windows authentication , impersonation , disabled anonymous access

-
suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
