SharePoint Stack Exchange is a question and answer site for SharePoint enthusiasts. It's 100% free, no registration required.

I have a webservice (no vcf) with Windows authentication(impersonate="true"), that uses the SharePoint 2013 Object Model.

When I call a webservice method that operates on a SharePoint Web Application with NTLM authentication (created with PowerShell) all goes well.

When I call a webservice method that operates on a SharePoint Web Application with Claims authentication (created with Claims authentication type: Enable windows authentication -> Integrated Windows authentication -> NTLM) all goes well only for the user of Central Admin Application Pool.

I make my user: Farm Admin, Site Collection admin, Site Owner, ... but nothing changes.

My caller is an Active Directory user with no Kerberos authentication enabled, but all the development environment is inside a single computer.

I am new to claims authenticaion. Do I have to modify the webservice code/web.config?

I have an error when I try to get Title/Name info inside the following code:

   spsSite = New SPSite(strUrl)
   If strUrl.Equals(spsSite.Url, StringComparison.OrdinalIgnoreCase) Then
         'strTitle = spsSite.RootWeb.Title
         strTitle = spsSite.RootWeb.Name
         …
         Return 0
   End If

Inside log I can see the following (System.UnauthorizedAccessException: Access is denied):

Can you try out claims/kerberos? Neither classic/ntlm nor claims/ntlm supports delegation. Potentially this is causing the access denied.

Also check out this post: Is Classic/NTLM based authentication a security riskfor Internet facing sites?
