I have Silverlight module on my site. This module takes data from stored procedure by webservices.

This module uses on some sub-portals (each portal has own administrator and users).

The problem: Module works correctly only for host-administrator or if I grant read rigths for every user.

For other users, module runs, but data receiving freezes and then we see such error:

Message: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details. at System.ComponentModel.AsyncCompletedEventArgs.RaiseExceptionIfNecessary()
at slchart.slchartasmx.GetSummaryListCompletedEventArgs.get_Result()
at slchart.MainPage.GetSummaryListCompleted(Object sender, GetSummaryListCompletedEventArgs e)
at slchart.slchartasmx.csDataServiceSoapClient.OnGetSummaryListCompleted(Object state)
Line: 1
Symbol: 1
Code: 0

As i can understand this is not a problem of silverlight module. It looks like webservices are denied for all users (except host-admin). Where in DNN5 possible to check access to page or module? Is there any solutions?

Thanks for answers...
