iFolder client on Windows fails to log in to a iFolder server 3.8.0.2 or earlier when password is changed. It locks the client account by re-trying with the old password.
To resolve this issue, add a entry to the Windows client registry @HKEY_CURRENT_USER\Software\Novell\iFolder\SupportOldServer and set the value to one. This provides support for connecting to older iFolder servers.
