i've a little problem with my sharepoint foundation 2010. when i create the portal, i choose the claims authentication because i want a form when the external partner want use my website.
when i try to implement the TSWebPart, remote app of windows server 2008 r2, sharepoint crash with this error:
The "TSPortalWebPart" Web Part appears to be causing a problem. Unable to cast object of type 'Microsoft.IdentityModel.Claims.ClaimsIdentity' to type 'System.Security.Principal.WindowsIdentity'.
Web Parts Maintenance Page: If you have permission, you can use this page to temporarily close Web Parts or remove personal settings. For more information, contact your site administrator.
i suppose a permission issue, but the sharepoint was created with a dedicated AD account and i can't resolve the problem.
what i can do?
