SQL XML Bulk Loader - Error connecting

I'm using the sqlxmlbulkloadlib to perform an xml bul开发者_Python百科k load. When integrated security=SSPI, the process completes fine inside a workflow hosted on my local machine in a wcf service. However, when that workflow is hosted on our server and kicked off from a service reference on an aspx page, the bulkloader produces an error connecting to the data source. I have tried using sql server authentication instead, but that fails even on my local machine with the same error connecting to data source.

My connection string looks like: "provider=SQLOLEDB;data source=Myserver;database=Mydb;User ID=Myuser;Password=Mypassword"

Ok, so after creating the sql account for the bulkloader, the policy required that I change the password. Didn't catch that till I tried logging in with the account in management studio.

I am curious, though, what I would have to do differently for integrated security to work from the production server.
