Office 365 v2 API Authorization code is malformed

Question

I've the following auth code copied from the browser for a user who granted our app to use their Office 365 email.

code=OAQABAAIAAADRNYRQ3dhRSrm-4K-adpCJ3J3UJ8GyC2qJDvNhlrUAObjph6sQ3A9waeQ5Tr-DA6WzxCdFbvadCRJw2S4a_lwA7MyelZWAPQZOlaB_X_1165CbmTXJMGioU6Cr0DhVTUzIlUv_-Svjp8DBrLVCxcDp5rJMM5mDNR0iGysuDIozWnOaPqCOl35NxPzyktrYK6D1MBptmXOPbhS-stTZXbHJr9gGE3FHzMU0XANXmTm30q4SPaoWPch-S1uFFL4xwS2oUv-lELBdcfIGh5UJBSraabGihVWUnbwBhh8eURSMRwryi7kubUcq0D27S-vIVZhtKopemQ1njAcExO58S7EgAyqbIzMxvmBXBe0X1ieVrcyHYRpt4ZAq1Z4v5HLTrYhx5fGp6AkqhV09yri3bqXaZvw5R1hKuhAbRDt_isZn_L8ZEhfwnqICGUwpDU27c6Qd1txuiOVY90a4BiAUh1M1u5gjDx8nIE88R7S915w7mUjJtCzZuTKQavve8q8UOtm9udUvBOX1f-bYslpgiIRbdSYBYlP9UrbreLS1W6OFk2NX-uqp9mabyImvvj1RUm166qV6uc9hsuhzrfErDURC17JotuQBSWYauAvb38p5B-cDbsCZafpyORlbrWsYyQcdWwUPL0aOZEQXFW-v3gDw7Xri_9hvsiHrj10NTaaozqm1QpZmMf-SHJ0yF9wBWKYgAA

Application works without a problem if we are using Microsoft Graph REST API v1 but the following problem happens when using version 2. It is registered with delegate permissions that grants us Read, Write/Send permission which work fine with V1 of the application.

For V2: authority =https://login.microsoftonline.com/common/oauth2/v2.0/token and to retrive auth code I use the following url

https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=30..7&response_type=code&scope=mail.read&redirect_uri=https://myurl:8443/controller/saveToken

Code block causing the issue:

 @Override
    public AuthenticationResult getToken(String authCode) {

        ExecutorService service = Executors.newFixedThreadPool(1);
        OfficeCredentials credentials = getCredentials();

        try {
            AuthenticationContext context = new AuthenticationContext(credentials.getAuthority(), true, service);
            final Future<AuthenticationResult> resultFuture = context.acquireTokenByAuthorizationCode(
                    authCode, new URI(credentials.getRedirectUri()), new ClientCredential(credentials.getClientId(),
                            credentials.getClientSecret()), credentials.getResourceUrl(), null);

            return resultFuture.get();//throws exception

        } catch (URISyntaxException e) {
            logger.error(e.getMessage());
        } catch (MalformedURLException e) {
            logger.error(e.getMessage());
        } catch (Exception e) {
            logger.error(e.getMessage());

        }

        return null;

    }

Exception when resultFuture.get() is called

java.util.concurrent.ExecutionException: com.microsoft.aad.adal4j.AuthenticationException: {"error_description":"AADSTS70000: Transmission data parser failure: Authorization Code is malformed or invalid.\r\nTrace ID: c37b4aba-c5fb-44f3-815c-dd798072095d\r\nCorrelation ID: e190ccd2-f98a-440c-8e79-69cfcead3c04\r\nTimestamp: 2017-02-06 17:53:30Z","error":"invalid_grant"}

I don't know what I am doing wrong as I am trying to migrate to v2. redirect_uri is same as defined in azure and it is HTTPS. I already made my local env't accept HTTPS by following this. FYI: I am using adal4 java library.

Answer 1

At present, the adal4j library doesn't support the Azure AD v2.0 endpoint(refer here). Event we set the authority for the v2.0 endpoint, it still use the old one.

As a workaround, you may compose the HTTP request directly. Here is the sample request for your reference( refer here):

POST: https://login.microsoftonline.com/{tenantId}/oauth2/v2.0/token

client_id={clientId}&client_secret={clientSecret}&scope={scope}&code={authorizationCode}&grant_type=authorization_code&redirect_uri={redirectUri}

And if you want the adal4j library to support Azure AD v2.0 endpoint, you can submit the feedback from here.
