Requires client registration 1 of Cyberduck in Settings → Admin → Authentication

redirect_uri's like x-cyberduck-action:oauth or x-mountainduck-action:oauth can't be registered, but x-cyberduck-action://oauth or x-mountainduck-action://oauth work fine:

• Allow redirect_uri's like "x-cyberduck-action:oauth" owncloud/oauth2#364 (comment)
