More ASP.NET problems

[martys]

I'm running into more problems running the project from ASP.NET. I call:

bld.SyncBuildEx(true, ident.Attributes["userName"].Value, "", ident.Attributes["password"].Value, false, false);

with good values for the userName and password (specifically, the username is "nt", just so we're clear). This user has permissions to edit files in a certain directory. However, when I run a step to edit a file in that directory, it fails with a "Access Denied" error. I added a Run Script step to show the username it's running under, and it says it's running under "Network Service". Is this to be expected? I would think it should be running as the user specified in the call to SyncBuildEx

Specifically, this is a Write XML step. I noticed that a Write Text step does not cause the same problem. (Also, this is the updated Write XML step that disables DTD verification)
