Any Idea?
I can't say i'm familiar with OneDrive for business, but from the error message it looks like the web application that hosts My Sites hasn't been configured for FBA. You might want to check this blog post, where I suggest using the machine.config for your membership+db connection entries, so it only has to be entered once instead of for each web application web.config:

You'll also have to make sure that the web application has been configured for FBA in central admin.
