Skydrive Pro - Credentials Not Remembered

Skydrive Pro - from Office 2013 install - pointed at a local Sharepoint 2013 server - will not remember credentials

Doesn't matter the combo - happens on a Windows 8 domain member computer where the credentials that are required on Skydrive are the same credentials just entered to log on to the domain

The check box to "Remember my credentials" does not work

Is this expected behavior ?

Something wrong in the Sharepoint server config ?

Thanks
