Hi Pavel,
This is not a typical problem that could occur in a Silverlight application.
Are you by any chance using
RadScriptManager on your page? If this is the case, you need to give access to its httpHandler, so it is available to all users, and just the authenticated users. This can be done by using the
<location> Element to specify different authentication settings for the
RadScriptManager's httpHandler. Please use similar code for your application as the one shown below, and if you have any problems, send us a sample project that demonstrates the issue. We would be glad to help.
Test either of the following:
