A minimal sample app using ADAL.JS and plain old vanilla JavaScript to obtain an access token from Azure Active Directory and use that access token to make an API request. In this case, the API we're requesting a token for is the Microsoft Graph API, which is used to retrieve the signed-in user's basic profile.

Hi @psignoret,
I'm trying the code above. Although I have entered my user information and logged in, I am constantly being redirected to the login page. I wonder why? Thank you
@bsungur-hub It's hard to say why without more details, but you really shouldn't be doing any new development with ADAL—you should use MSAL.JS instead.
Thanks for this sample which is working on the first try while the official doc at https://github.com/AzureAD/azure-activedirectory-library-for-js is full of typos and missing comments/examples!
