Profile Import fails when running Central Administration over SSL - Wahids SharePoint Blog
The issue occurs only when using the new SharePoint Active Directory Import in SharePoint 2013 when your Central Administration site is running over SSL. When you first setup your profile sync, you have three choices under “Configure Synchronization Settings”:
1.Use SharePoint Profile Synchronization (This one leverages the built-in FIM)
2.Use SharePoint Active Directory Import (This is the direct AD Import)
3.Enable External Identity Provider
