I regularly use Visual Studio Online (unfortunately mis-named by Microsoft - it should really be named "TFS Online" because that's what it really is) as my version control system (VCS) with Visual Studio 2013 and Visual Studio 2015 from several computers with no trouble (i.e., can add new projects, check-in, check-out, create shelve sets, etc.).
However, I cannot figure out the correct values to plug into IntelliJ 14.1.4 Ultimate's dialog that appears when I traverse VCS / TFS / Edit Configuration... / Add ...
I don't want to expose my true URI that I use to connect to Visual Studio Online, but assume for the sake of this question that it is abc.visualstudio.com/DefaultCollection and that, when I view it from inside Visual Studio, I see a top-level folder named TrainingAndDemos with all my "projects" underneath.
After I click the Add ... button in the IntelliJ dialog, I'm presented a modal popup form with the following boxes (some of which remain disabled until I change the Auth: dropdown listbox).
Auth: choices are NTLM (system credentials), NTLM or Alternate.
 save password checkbox
I have tried various combinations of Address (with and without http: or https: prefix), Auth, User Name and, of course, password, but always get the following error, no mater what combination of entries I type into that dialog:
Host contacted, but no TFS service found.
Is there some place with a detailed, step-by-step example I can follow? I've search your site, but cannot find that type of information.
