Variaciones Sharepoint 2007 errores con autenticación Forms

 

Today we were fighting with Santiago and Javier in an error caused by the variations in Sharepoint 2007 in a portal with authentication forms (FBA). During this fight we were received the following errors:

  • Tipo de excepción: HttpException
        Mensaje de la excepción: El servidor no puede modificar cookies después de enviar los encabezados HTTP.
  • System.Web.HttpCookieCollection.Add(HttpCookie cookie)
       en System.Web.Security.RoleManagerModule.OnLeave(Object source, EventArgs eventArgs)
       en System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
       en System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
  • Exception information:
    Exception type: HttpException
    Exception message: Cannot redirect after HTTP headers have been sent.
    at System.Web.HttpResponse.Redirect(String url, Boolean endResponse)
    at System.Web.Security.FormsAuthenticationModule.OnLeave(Object source, EventArgs eventArgs)
    at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute()
    at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

When we tried to access the site we received the following message “401 UNAUTHORIZED” and we found the solution for this problem in http://www.codeplex.com/MOSSFormsFeature/Thread/View.aspx?ThreadId=9702 and we solved the issue putting the attribute “batch=false” in the web.config of application web.

Santiago, Javier y Fabián
