HTTP 401 Error while using SSP in Project Web Access

Hi,

I am working on a requirement which requires updating the actual hour
against resources and actual cost against the task for a particular projcet.

We are using Statusing web service to update the actual hour of the
resources on date basis.

We are using status method to update the actuals.

We can only invoke this method if the user is an administrator otherwise we
encounter General Security Exception. And only the resource can update
his\her own actuals. if using some other resource account we try to update
the actuals we again get General Security Exception.

Currently we are using a single dedicated account to call the web service
and method. After googling we came up with impersonation to actually update
the actuals for all the resources using a single dedicated account. We are
trying to achieve impersontaion in PSI using SSP in Project Server.

But while calling SSP from my .net component which runs on the Project
Server where PWA is hosted i am getting HTTP 401 error.

The account which i am using to call the SSP web service has administrator
previliges in Project Web Access.

Please suggest me the resolution. Please do the needful.
