I am trying to pull azure ad user info using azure AD graph api. Will graph api work with adal 2 nuget packages?
Reason for this question is My webapplication is using below code in for auth and works only with Adal2x versions using Microsoft.IdentityModel.Clients.ActiveDirectory.
But Azure ad graph uses different way to pull token and it works only with adal3 .AcquireTokenSilentAsync is part of adal3. AcquireTokenByAuthorizationCode is part of adal2 for authentication on startup. I have to use both authentication and graph api. Is there any option to user graph api with adal2x version to match both?
public void ConfigureAuth(IAppBuilder app)
{
ApplicationDbContext db = new ApplicationDbContext();
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
Authority = Authority,
PostLogoutRedirectUri = postLogoutRedirectUri,
Notifications = new OpenIdConnectAuthenticationNotifications()
{
//If there is a code in the OpenID Connect response, redeem it for an access token and refresh token, and store those away.
AuthorizationCodeReceived = (context) =>
{
var code = context.Code;
ClientCredential credential = new ClientCredential(clientId, appKey);
string signedInUserID = context.AuthenticationTicket.Identity.FindFirst(ClaimTypes.NameIdentifier).Value;
AuthenticationContext authContext = new AuthenticationContext(Authority, new ADALTokenCache(signedInUserID));
//AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode(
//code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);
AuthenticationResult result = authContext.AcquireTokenByAuthorizationCode(
code, new Uri(HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Path)), credential, graphResourceId);
return Task.FromResult(0);
}
}
});
}

public async Task<ActionResult> Index()
{
UserProfile profile;
string tenantId = ClaimsPrincipal.Current.FindFirst(TenantIdClaimType).Value;
AuthenticationResult result = null;
try
{
// Get the access token from the cache
