[O] orgmode 9.x refile not working any longer with ido

[Jerome Gay]

Hi all,

Apologies in advance as this is my first post here. I'm sharing my problem with you all after posting to stackoverflow 

Since I upgraded orgmode to 9.x, refile is no longer working with ido. According to http://orgmode.org/Changes.html, all options related to ido and iswitchb have been removed. It also mentions "Instead Org uses regular functions, e.g., completion-read so as to let those libraries operate."

However, being a recent vim-user-turned-emacs, I can't find how to setup ido (including ido-vertical) to work in orgmode 9.x the way it used to work in 8.x 

Any suggestion welcome. Thanks in advance.

Cheers /jerome
