Since your infosec will not allow SQL based authentication, the USER that is invoking your script will need to have priviledges to the database you are attempting to access.
Please discover what user id is being used to call your script, then check that the SQL server is set for "NT authentication", and that user has been allowed access. See http://msdn.microsoft.com/en-us/library/ms188670.aspx
You can also examine the SQL ERRORLOG file at %programfiles%\Microsoft SQL Server\INSTANCE\mssql\log\ERRORLOG for more details. (See this msdn blog post)
