Good morning,
I'm using the application "Fiddler - HTTP Debugging Proxy" to test communication with the service from Silverlight "OlapManager.svc / binary". Which is published in IIS 7.

The published program is using the component OlapClient, to connect the SSAS.

When attempting to communicate, is giving 401 error when accessing the service.

What should I do to communicate properly?
- There is enabled anonymous access in IIS.
- I can view the service via the service via URL.
- The folder is full with permission for all users.
- I have already put the files and ClientAccessPolicy CrossDomain.

Hi Clay,

Thanks for your interest in Syncfusion Products.

Please refer some of the possible ways in which the authentication issue (401 error) raised with its solutions below:

1) When there is an binding mismatch between the web.config file custom binding endpoint address and the application EndPointAddress.

Please refer the following link:


2) When your remote WCF service configuration does not appear to be in sync with your IIS authentication setup.

Please have a look at the below link for the above issue:


Please refer other links for the 401 authentication issue:

My setup is as shown in the example of component of Syncfusion. And also within the WCF service code.

My IIS is allowing authenticated access by Windows.

If useful, see the link to the information on my problem (in Portuguese).
