setting a parameter in Exchange Profile

Hi

I am following Ravi's weblog

Different types of Mapping in XI------/people/ravikumar.allampallam/blog/2005/02/10/different-types-of-mapping-in-xi

I have set a parameter in the exchange Profile of XI. When I did login using XISUPER and set the parameter but its not reflecting in the Interface mapping option.

On which user ID I have to login and set parameter ?

Thanks
