Can't attach debugger on a citrix machine for ASP.NET 1.1 app

Question

 We have a citrix server set-up for development. When trying to attach a debugger or debug our ASP.NET 1.1 application we get an error cannot attach debugger. I'm sure it's a security settings as when our admin try to do that he can attach the debugger with no problems.

We cannot have administration rights to the box - so what kind of security settings or policy our admin needs to provide the developers in order to debug our ASP.NET application?
