I've actually never had an issue with the SSIS task, from my perspective it works perfectly. What kinds of issues have you encountered sqlBuddy?
I set up the task:
LoginsToTransfer = SelectedLogins
LoginList = (Collection)
IfObjectExists = Skip
CopySids = True
Works like a charm. Albeit, I've never tested the accounts further than connecting to the DB and running a simple SELECT query, but it did work.
