adal:1.16.+ ErrorCode:invalid_grant. (working for adal 1.14)

[amitse]

Expected behavior

_authenticationContext.acquireToken(activity, resource, clientId, redirectUri, PromptBehavior.Auto, handler )

must return valid token for 'com.microsoft.aad:adal:1.16.+'

Actual behavior

We have been using 'com.microsoft.aad:adal:1.16.+' for our android app for quite some time now.

Starting 1200hrs UTC 30th October our published app using 'com.microsoft.aad:adal:1.16.+' started failing with error (acquireToken method)

[Error: Request authority:https://login.microsoftonline.com/ clientid: ErrorCode:invalid_grant]

Steps to reproduce the problem

create a sample application with adal 1.16,

        AuthenticationContext  mAuthContext = new AuthenticationContext(getCurrentActivity(), authority, true);
 mAuthContext.acquireToken(getCurrentActivity(), resource, clientId, redirectUri, PromptBehavior.Auto,
                        new AuthenticationCallback<AuthenticationResult>() {
....
}

Specifications like the version of the library, operating system etc.

'com.microsoft.aad:adal:1.16.+'

Relevant logs and traces

[Error: Request authority:https://login.microsoftonline.com/ clientid: ErrorCode:invalid_grant]

Workaround

For now reverting the library to version 1.14 seems to work and all the android apps are receiving valid token

• MSAL or ADAL? -> ADAL
• Brokered Authentication? -> No
