NDS connections

Is there any way to get all NDS connection for a workstation from service?
I need to monitor NDS connections for all users in my service. But CLib
function NWCCScanConnRefs works only under current user account.

Peter Kuo has already answered me (on Novell Discussion Server):
"When run from a service, you need to seperately authenticate into DS,
regardless if the workstation is already logged in or not."

I tried to do so. So i authenticated in service into NDS, but
NWCCScanConnRefs still dosn't return all workstation connections - only
that one that i used in service for authentication.
