TS2503: Cannot find namespace 'adal'

[negberts]

The example doesn't appear to work.

node_modules/angular2-adal/services/adal.service.d.ts(13,25): error TS2503: Cannot find namespace 'adal'.

Edit:
I fixed it by adding "adal": "github:DefinitelyTyped/DefinitelyTyped/adal-angular/adal.d.ts#53347571e6f44ed9a961b569bb81893fde4789c1" to typings.json

This issue still exists if you run the solution with Visual Studio 2015
