Error when creating a SOAP Data Source in SharePoint
Designer
With Microsoft SharePoint
Designer 2010, you can easily link data sources that contain interrelated data
to one another. You can even link data sources of separate types — for example,
you can link an XML file to an SQL database. By linking multiple data sources,
you create a single data source that appears in the Data Sources list with all
of your other data sources.
Consider the following scenario:
§ You create a web application which is
configured to use claims-based authentication with NTLM
§ You create a custom list or use an existing
list with some data.
§ You create a SOAP data source in SharePoint
Designer & configure to authenticate as a claims user
In this scenario, you receive an error similar to the
following
The server returned a non-specific error
when trying to get the data view from the data source
Cause: I am
trying to find out the root cause behind this issue but most probably the answer
would be- SharePoint
impersonates the anonymous IIS user account and is denied access to the
resource.
Resolution:
1.
Open
IIS Manager.
2.
Expand
site and find the application to which you are connecting from SharePoint
Designer.
3.
Right
click, select Explore.
4.
Open
the web.config file
5.
Search
for <appSettings>
6.
Find
the line with <add key="aspnet:AllowAnonymousImpersonation"
value="true" />
7.
Change
it to <add key="aspnet:AllowAnonymousImpersonation"
value="false" />
8.
Save
the file
9.
Add
the Data View from SharePoint designer.
