iis 7 - Sharepoint 2010 Custom Web Service - The HTTP request is unauthorized with client authentication scheme 'Ntlm' -

-

i have 2 custom web services built on top of sharepoint. switched servers , upgraded site 2008 2010 on weekend. following errors on each web service when viewed through .net web service wrapper.

system.servicemodel.security.messagesecurityexception: http request unauthorized client authentication scheme 'ntlm'. authentication header received server 'ntlm'. ---> system.net.webexception: remote server returned error: (401)

and

system.net.webexception: request failed http status 401: unauthorized.

the web services have dlls live in gac , asmx files live in layouts hive folder. these worked fine before upgrade/server move.

what think happening default windows credentials aren't being passed service. web service calls sharepoint web services list content.

here's example of 1 of calls returns 401:

<webmethod()> _ public function testgetuserinfo() string     dim userservice new sharepointuser.usergroup     userservice.credentials = system.net.credentialcache.defaultcredentials      dim userinfoxml xmlnode = userservice.getuserinfo(user.identity.name)      return userinfoxml.childnodes(0).attributes("name").value end function

this call goes against: http://{domainname}/_vti_bin/lists.asmx?wsdl

i've verified user.identity.name returns correct logged in user info. think it's system.net.credentialcahche.defaultcredentials that's not working. i've tried .defaultnetworkcredentials no luck.

this have in web.config:

  <system.servicemodel> <servicehostingenvironment aspnetcompatibilityenabled="true" /> <bindings>   <basichttpbinding>     <binding name="projectbasichttpconf" closetimeout="00:01:00" opentimeout="00:01:00" receivetimeout="00:10:00" sendtimeout="00:01:00" allowcookies="true" maxbuffersize="4194304" maxreceivedmessagesize="500000000" messageencoding="text" transfermode="streamedresponse">       <security mode="transportcredentialonly">         <transport clientcredentialtype="windows" proxycredentialtype="none" realm="" />         <message clientcredentialtype="username" algorithmsuite="default" />       </security>     </binding>     <binding name="basichttpbindingwithwindowsauthentication">       <security mode="transportcredentialonly">         <transport clientcredentialtype="windows" proxycredentialtype="none" />         <message clientcredentialtype="username" algorithmsuite="default" />       </security>     </binding>     <binding name="spfilesaccessservicesoap" closetimeout="00:01:00" opentimeout="00:01:00" receivetimeout="00:10:00" sendtimeout="00:01:00" allowcookies="false" bypassproxyonlocal="false" hostnamecomparisonmode="strongwildcard" maxbuffersize="65536" maxbufferpoolsize="524288" maxreceivedmessagesize="65536" messageencoding="text" textencoding="utf-8" transfermode="buffered" usedefaultwebproxy="true">       <readerquotas maxdepth="32" maxstringcontentlength="8192" maxarraylength="16384" maxbytesperread="4096" maxnametablecharcount="16384" />       <security mode="transportcredentialonly">         <transport clientcredentialtype="windows" proxycredentialtype="none" realm="" />         <message clientcredentialtype="username" algorithmsuite="default" />       </security>     </binding>   </basichttpbinding> </bindings> <behaviors>   <endpointbehaviors>     <behavior name="clientendpointbehavior">       <clientcredentials>         <windows allowedimpersonationlevel="impersonation" />       </clientcredentials>     </behavior>   </endpointbehaviors> </behaviors>

under system.web:

<authentication mode="windows" /> <identity impersonate="true" />

i've gone , forth anonymous authentication no luck.

in iis have windows authentication enabled , ntlm provider.

any ideas on how fix this? reading.

-nate

i never figured out. did workaround called microsoft.sharepoint namespace stuff directly instead of calling web service. bypassed security issues.

c# - How to set Z index when using WPF DrawingContext? -

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

-
i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...
