Ok next follow-up question. In the mid server extension section I believe you have to provide it a username/password if you select basic authentication right? I believe that links back to a credential record in ServiceNow so make sure that the username and password matches that credential entry. It won't be an account within ServiceNow it's specifically the credential chosen on that extension form (I do apologize for being vague as I have only done this once and it was a while ago and I don't have access to my PDI at the moment to check).
