Unable to get Trace Logging to work in MDS 2014

Hi,

I'm trying to get the application logging to work, but nothing is happening. I'm using SQLServer2014.

I've followed the instructions on http://support.microsoft.com/kb/2423478 , even copying and pasting the snippet into web.config, but nothing happens, no log is created in the default directory.

Is there something version specific? Does 2014 behave differently?

Thanks

James
