We currently have a few pages that use RadAjaxManagers on them in a project that uses the ASP.NET membership authentication system.
This system has been working fine, however when a user is logged in and either is disabled (user.IsApproved = False / put into Disabled User role) or is removed from the role needed to access the page they are on, the membership then redirects them to an error page. When this happens the user triggers an Ajax request the following error pops up.
Webpage error details

How can we get the authentication and role system built into ASP.Net 2.0 to play nicely with the RadAjaxManager and properly handle the situations described above? The system currently works fine as long as teh RadAjaxManager is not involved.
We do have the following in the web.config, btu still get the error:
| <location path="WebResource.axd"> |
| <system.web> |
| <authorization> |
| <allow users="*"/> |
| </authorization> |
| </system.web> |
| </location> |
| <location path="Telerik.Web.UI.WebResource.axd"> |
| <system.web> |
| <authorization> |
| <allow users="*"/> |
| </authorization> |
| </system.web> |
| </location> |
| <location path="ScriptResource.axd"> |
| <system.web> |
| <authorization> |
| <allow users="*"/> |
| </authorization> |
| </system.web> |
| </location> |

Could you please confirm that you are not making calls like Response.Write(), response filters, HttpModules and server is not enabled as mentioned in the error message?
Additionally, I suggest that you try handling the errors with ajax as described here.
Check it out and let me know how it goes.

The error can be thrown due to different problems. And there is no straight forward resolution for it. To solve it in your case, we will need to find what is causing it in your specific case. Can you send us a live Url with the problematic page code and steps for replicating the problem? We will check it out and turn back to you with our finding.
You can open a formal support ticket if it is not applicable for you to share the required information in the forum.
