Unable to run signtool action as an another user

I am trying to run the signtool action after an successfull build.

I want to run the signtool.exe as a specific domainuser and I have given this user all needed rights needed for an XP client

· Act as part of the operating system
· Create a token object
· Replace a process-level token
· Adjust memory quotas for a process  

 

I always receive the error "Error: The stub received bad data" as shown below

Error executing program : Failed to execute program "C:\Program Files\Microsoft SDKs\Windows\v7.0A\bin\signtool.exe" sign /t http://timestamp.verisign.com/scrip...mstamp.dll C:\BuildOutput\\20110511.2\Build\AddCustomer.Layout.dll  as user codesign. Error : The stub received bad data

Has anyone run into this?

It looks like the domain user cannot run any executables on the machine.  If I login as this same domain user on the machine I can run signtool.exe with the same parameters without a problem.
