A customer is experiencing a problem which seems to be related to the Razor Mediator.
They have a template which makes use of a webdav connection in it. When they publish a page using the template they get the following error:
RazorHandler: Error import of '/webdav/500%20Public%20bpfBOUW%20Website/Building%20Blocks/System/Templates/000%20Algemeen/RPT_test_imports_lho.cshtml'. Tridion.ContentManager.AccessDeniedException: Impersonation by this user requires the NT AUTHORITY\SYSTEM account to be configured as impersonation user. at Tridion.ContentManager.Security.AuthorizationManager.GetImpersonationUserSettings(String name) at Tridion.ContentManager.Security.AuthorizationManager.LoadAccessToken(String userName, String impersonationUserName) at Tridion.ContentManager.Session..ctor(String userName) at Tridion.Extensions.Mediators.Razor.RazorHandler.get_Session() at Tridion.Extensions.Mediators.Razor.RazorHandler.GetImportTemplateContent(String path)
User: NT AUTHORITY\SYSTEM
When adding the NT AUTHORITY\SYSTEM account to the impersonation users, the errormessage is not thrown anymore. The question is why there is a need to add this user to the impersonation users?
