If you are using our Full federation Service then Cloud Drive Mapper will single sign on without any issues. You can also configure Single Sign On with ADFS on premises.
If your ADFS is using Windows Integrated Authentication then Cloud Drive Mapper will identify this and automatically set up the Single Sign On. It is only if the email / UPN is different will you need some REG keys which are listed on page 20 of the Cloud Drive Mapper deployment guide.
