Can you please help me about this ?

I try to put this ressource kit tool in Hyena in order to find user's group membership.

The difficulty is that the parameter of this command must be reached with the server name and the user name. It should be a command like this i suppose :

findgrp \\[server name] %E%(for user) /l (for local group search)

Can you help me please ?

Thank you in advance,
