We use to create email delegates through Google Email Settings API, but after the deprecation of OAuth 1.0 we were no longer able to authenticate properly. After doing some research I think we should create a service account, delegate domain-wide access for that service account, then authenticate using it. However I can't seem to get it to work, all I receive from Google is 401 unauthorized. Does someone know what I am doing wrong? Here is most of the code, I'm using .Net/c# and I'm using Google Apps for business.
ServiceAccountCredential credential = new ServiceAccountCredential(new ServiceAccountCredential.Initializer("serviceAccountEmail")
{
Scopes = new[] { "https://apps-apis.google.com/a/feeds/emailsettings/2.0/ " },
User = "admin email string"
}.FromCertificate({X509 certificate from service account p12 file}));
credential.RequestAccessTokenAsync(System.Threading.CancellationToken.None).Wait(-1);
GoogleMailSettingsService service = new GoogleMailSettingsService("domain name", "appname");
service.SetAuthenticationToken(credential.Token.AccessToken);
service.CreateDelegate("delegator", "delegate");
For those who may need this answer in the future, I was able to provide a solution through the following. For reference I am running a web app using MVC framework, but the solution could be tweaked for a console or GUI standalone app as well.
Basically, I was able to authenticate the GoogleMailSettingsService.Service.RequestFactory with a GOAuth2RequestFactory object.
For instance:
GoogleMailSettingsService service = new GoogleMailSettingsService("domain", "applicationName");
service.RequestFactory = new GOAuth2RequestFactory("service", "AppName", new OAuth2Parameters() { AccessToken = AuthorizationCodeWebApp.AuthResult.Credential.Token.AccessToken });
Now for the AuthorizationCodeWebApp.AuthResult I implemented the following:
public async Task<ActionResult> DelegationMenu(CancellationToken cancellationToken)
{
var result = await new AuthorizationCodeMvcApp(this, new AppFlowMetadata()).AuthorizeAsync(cancellationToken);
if (result.Credential == null)
return new RedirectResult(result.RedirectUri); //Will redirect to login page for Google Admin to authenticate.
Session["AuthResult"] = result;
return View();
}
public class AppFlowMetadata : FlowMetadata
{
private static readonly IAuthorizationCodeFlow flow =
new GoogleAuthorizationCodeFlow(new GoogleAuthorizationCodeFlow.Initializer
{
ClientSecrets = new ClientSecrets
{
ClientId = "ClientId",
ClientSecret = "ClientSecret"
},
Scopes = new[] { "https://apps-apis.google.com/a/feeds/emailsettings/2.0/" },
DataStore = new FileDataStore("C:\\OAuth2.0Tokens")
});
public override string GetUserId(Controller controller)
{
var user = controller.Session["user"];
if (user == null)
{
user = Guid.NewGuid();
controller.Session["user"] = user;
}
return user.ToString();
}
public override IAuthorizationCodeFlow Flow
{
get { return flow; }
}
}
A service account isn't required for this action. The Email Settings API, within the Admin SDK, allows a Super Admin to set a delegation for an account within the domain without the need to impersonate the user via a service account.
Check out this section of the Developers site for more information on this API. You can also test this on the OAuth Playground and add delegates right from there.

I use token auth for my WebApi application.
I have the following ConfigureAuth method in Startup class:
// Configure the application for OAuth based flow
PublicClientId = "self";
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/Token"),
Provider = new ApplicationOAuthProvider(PublicClientId),
AuthorizeEndpointPath = new PathString("/api/Account/ExternalLogin"),
AccessTokenExpireTimeSpan = TimeSpan.FromDays(14),
// In production mode set AllowInsecureHttp = false
AllowInsecureHttp = true
};
// Enable the application to use bearer tokens to authenticate users
app.UseOAuthBearerTokens(OAuthOptions);
and ApplicationOAuthProvider:
public class ApplicationOAuthProvider : OAuthAuthorizationServerProvider
{
private readonly string _publicClientId;
public ApplicationOAuthProvider(string publicClientId)
{
if (publicClientId == null)
{
throw new ArgumentNullException("publicClientId");
}
_publicClientId = publicClientId;
}
public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
{
var userManager = context.OwinContext.GetUserManager<ApplicationUserManager>();
var user = await userManager.FindAsync(context.UserName, context.Password);
//ApplicationUser user = new ApplicationUser() { UserName ="a" };
if (user == null)
{
context.SetError("invalid_grant", "The user name or password is incorrect.");
return;
}
ClaimsIdentity oAuthIdentity = await user.GenerateUserIdentityAsync(userManager,
OAuthDefaults.AuthenticationType);
ClaimsIdentity cookiesIdentity = await user.GenerateUserIdentityAsync(userManager,
CookieAuthenticationDefaults.AuthenticationType);
AuthenticationProperties properties = CreateProperties(user.UserName);
AuthenticationTicket ticket = new AuthenticationTicket(oAuthIdentity, properties);
context.Validated(ticket);
context.Request.Context.Authentication.SignIn(cookiesIdentity);
}
so, I should call /Token and pass credentials to get token. It works, but I want to create Unit Test for it. Is it possible?
The only way to do that is by make an integration test, which asserts the full pipeline testing - from request to response. Before the actual test on the server, you can call the token endpoint to get it, and then use it in the actual unit test by attaching it to the response. I have a sample, which uses MyTested.WebApi here:
Sample
You can do the same without the testing library, this is just how to do it.
I like the idea of pluggable configuration.
For Unit Test project, I want to use specific identity and get predictable data fro LDAP. So, i use the following line in my unit test method when setting http configuration:
config.Filters.Add(new WebApiSetIdentityFilter(config, identityName));
where the filter just "hacks" the identity, replacing the fields I need:
public async Task AuthenticateAsync(HttpAuthenticationContext context, CancellationToken cancellationToken)
{
//This principal flows throughout the request.
context.Principal = new GenericPrincipal(new GenericIdentity(this.IdentityName, "LdapAuthentication"), new string[0]);
}
I need to utilize Dynamic CRM Data Service Endpoint exposed to get data from one of the methods.
Service(microsoft) account has access to this service.
I've tried authenticating to Discovery Service and Organization Service using sample code provided here [https://msdn.microsoft.com/en-us/library/hh675404.aspx] and succeed. However am not able to use same authentication to access data Service as I could find anyway to relate Data Service with the other two. Doing basic authentication using Network Credentials does not work.
I have downloaded the CSDL exposed and added that as service reference to my project, which created an class of web service which extends from DataServiceContext. Am trying to retrieve data of one of the methods using LinQ queries. It returs following error:
"The response payload is a not a valid response payload. Please make sure that the top level element is a valid Atom or JSON element or belongs to 'http://schemas.microsoft.com/ado/2007/08/dataservices' namespace." On capturing using fiddle I realized that on hitting data service URL it is redirected to sign in page 'login.microsoftonline.com/'
Can anybody suggest a way to authenticate the user to access Data Serivce?
Adding code:
//<snippetAuthenticateWithNoHelp1>
IServiceManagement<IDiscoveryService> serviceManagement =
ServiceConfigurationFactory.CreateManagement<IDiscoveryService>(
new Uri(_discoveryServiceAddress));
AuthenticationProviderType endpointType = serviceManagement.AuthenticationType;
// Set the credentials.
AuthenticationCredentials authCredentials = GetCredentials(serviceManagement, endpointType);
String organizationUri = String.Empty;
// Get the discovery service proxy.
using (DiscoveryServiceProxy discoveryProxy =
GetProxy<IDiscoveryService, DiscoveryServiceProxy>(serviceManagement, authCredentials))
{
// Obtain organization information from the Discovery service.
if (discoveryProxy != null)
{
// Obtain information about the organizations that the system user belongs to.
OrganizationDetailCollection orgs = DiscoverOrganizations(discoveryProxy);
// Obtains the Web address (Uri) of the target organization.
organizationUri = FindOrganization(_organizationUniqueName,
orgs.ToArray()).Endpoints[EndpointType.OrganizationService];
}
}
//</snippetAuthenticateWithNoHelp1>
if (!String.IsNullOrWhiteSpace(organizationUri))
{
//<snippetAuthenticateWithNoHelp3>
IServiceManagement<IOrganizationService> orgServiceManagement =
ServiceConfigurationFactory.CreateManagement<IOrganizationService>(
new Uri(organizationUri));
// Set the credentials.
AuthenticationCredentials credentials = GetCredentials(orgServiceManagement, endpointType);
// Get the organization service proxy.
using (OrganizationServiceProxy organizationProxy =
GetProxy<IOrganizationService, OrganizationServiceProxy>(orgServiceManagement, credentials))
{
// This statement is required to enable early-bound type support.
organizationProxy.EnableProxyTypes();
// Now make an SDK call with the organization service proxy.
// Display information about the logged on user.
Guid userid = ((WhoAmIResponse)organizationProxy.Execute(
new WhoAmIRequest())).UserId;
SystemUser systemUser = organizationProxy.Retrieve("systemuser", userid,
new ColumnSet(new string[] { "firstname", "lastname" })).ToEntity<SystemUser>();
Console.WriteLine("Logged on user is {0} {1}.",
systemUser.FirstName, systemUser.LastName);
Uri x = new Uri("https://<MyOrgainzationName>.crm.dynamics.com/XRMServices/2011/OrganizationData.svc/");
MyOrgainzationContext saContext = new MyOrgainzationContext(x);
NetworkCredential nc = new NetworkCredential();
nc.UserName = "*****#microsoft.com";
nc.Password = "********";
saContext.Credentials = nc;
var query_where3 = from c in saContext.new_productSet
select new
{
ProductStatus = c.new_ProductStatus,
LineofBusiness = c.new_LineofBusiness
};
var temp = saContext.Entities;
foreach (var c in query_where3)
{
System.Console.WriteLine("ProductStatus: " +
c.ProductStatus +
"\t\t\t" +

c.LineofBusiness);
}

MyOrganizationContext is the context class created on adding CSDL file exposed at service endpoints
Have a look at the CRM Web Api Preview: https://msdn.microsoft.com/en-us/dynamics/crm/webapipreview.aspx. You can call this endpoint from outside xRM and you can authenticate with OAuth 2.0.
We migrated a multitenant MVC application from ASP.NET Membership Provider to ASP.NET Identity.
This is my Startup.Auth.cs (simplified):
public partial class Startup
{
public void ConfigureAuth(IAppBuilder app)
{
app.CreatePerOwinContext<ApplicationUserManager>(ApplicationUserManager.Create);
app.CreatePerOwinContext<ApplicationSignInManager>(ApplicationSignInManager.Create);
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
Provider = new CookieAuthenticationProvider
{
OnValidateIdentity =
SecurityStampValidator.OnValidateIdentity<ApplicationUserManager, Identity, int>(
TimeSpan.FromMinutes(30),
(manager, user) =>
manager.CreateIdentityAsync(user, DefaultAuthenticationTypes.ApplicationCookie),
clIdentity => clIdentity.GetUserId<int>())
}
});
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
}
In our multitenant application, each tenant has its own 'slug' (e.g. http://example.com/tenant1/ and http://example.com/tenant2/)
However, currently, the cookies are stored in the root. This causes security issues as users from tenant1 are automatically logged in on the website from tenant2.
How can we make the CookiePath (in CookieAuthenticationOptions) variable so that it changes depending on the tenant?
I fixed this issue with a lot of help from dampee.
The CookiePath in the CookieAuthenticationOptions object is evaluated only once: at application startup.
The easiest solution (workaround) was to create a derived CookieAuthenticationProvider that overrides ResponseSignIn and ResponseSignOut.
They both have an argument called context which has a property called CookiePath. Modify this property in both of these methods to change the CookiePath.
You can also use the class I created.
Then all you have to do is replace the CookieAuthenticationProvider in the CookieAuthenticationOptions with the one you just created.
This works for the ApplicationCookie. The ExternalSignInCookie doesn't matter that much since it is used only temporarily while signing in with an external login.
Improving on SamuelDebruyn's own solution, I found you can pass the path from the SignIn call to the provider using an AuthenticationProperties object. This way, instead of extracting the path from the request context as his gist shows, you can pass it explicitly from the source:
// method inside web api controller
private void SignIn(string name, string cookiePath)
{
var claims = new[] { new Claim(ClaimTypes.Name, name) };
var identity = new ClaimsIdentity(claims, "ApplicationCookie");
var options = new AuthenticationProperties();
options.Dictionary["CustomCookiePath"] = cookiePath;
var authManager = Request.GetOwinContext().Authentication;
authManager.SignIn(options, identity);
}
// Startup.cs
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
Provider = new CustomCookieProvider()
});
// custom provider
public class CustomCookieProvider : CookieAuthenticationProvider
{
public override void ResponseSignIn(CookieResponseSignInContext context)
{
context.CookieOptions.Path = context.Properties.Dictionary["CustomCookiePath"];
base.ResponseSignIn(context);
}
}
You can use a custom ICookieManager to dynamically return the cookie value to the CookieAuthenticationProvider based on whatever is in the request, to do this you would still maintain the CookiePath as "/" and then leave it up to the ICookieManager to return (or write) the cookie however you want. The CookieManager is an option on the CookieAuthenticationOptions. I blogged about this here: http://shazwazza.com/post/owin-cookie-authentication-with-variable-cookie-paths/
I am using below piece of code to list all domain users in my simple Console application
var certificate = new X509Certificate2("D:\\3acf2c2008cecd33b43de27e30016a72e1482c41-privatekey.p12", "notasecret", X509KeyStorageFlags.Exportable);
var privateKey = certificate.Export(X509ContentType.Cert);
var provider = new AssertionFlowClient(GoogleAuthenticationServer.Description, certificate)
{
ServiceAccountId = "877926787679-b7fd15en1sh2oc65e164v90cfcvrfftq#developer.gserviceaccount.com",
Scope = DirectoryService.Scopes.AdminDirectoryUserReadonly.GetStringValue(),
ServiceAccountUser = "user1#05.mygbiz.com"
};
var auth = new OAuth2Authenticator<AssertionFlowClient>(provider, AssertionFlowClient.GetState);
DirectoryService dirService = new DirectoryService(new BaseClientService.Initializer()
{
Authenticator = auth,
ApplicationName = "My APP"
});
Users users = dirService.Users.List().Execute();
Execute() method errors out saying Bad Request.
Questions:
How to overcome this issue?
Does this Admin SDK support trial version of Google APP account?
I have updated service account Client ID in Google Console and also updated in Admin Console with below scopes
https://www.googleapis.com/auth/admin.directory.group
https://www.googleapis.com/auth/admin.directory.user
and also set API access check box. Do I missing something in settings?
Like JoBe said, you should include the domain parameter.
happy_user = service.users().list(domain='mydomain.com').execute()
This has worked for me.
I'm looking for a way to authenticate a user (given a username and password) via the Microsoft CRM 4.0 Web Services API. Ideally, I'd like to filter down a list of projects based on which ones the logged in user has access to. i may be able to figure out the second part but I can't find a way to authenticate the user. The way all of the cals are currently made in the web service is via:
MyWebServices.CrmService svc = new MyWebServices.CrmService();
MyWebServices.CrmAuthenticationToken token = new MyWebServices.CrmAuthenticationToken();
token.OrganizationName = "MyCRM";
token.AuthenticationType = 0;
svc.CrmAuthenticationTokenValue = token;
svc.PreAuthenticate = true;
svc.Credentials = System.Net.CredentialCache.DefaultCredentials;
svc.Credentials = new NetworkCredential("hj", "mypass", "mydomain");
Then calls can be made via the service. I guess I could potentially try to authenticate to CRM via the user's username/password but it feels wrong somehow.
If you are in an on-premise environment, you should be able to use the following code to get a valid CRM service that can be used to retrieve your projects.
public static Microsoft.Crm.SdkTypeProxy.CrmService GetCrmService(string crmServerUrl, string organizationName, System.Net.NetworkCredential networkCredential)
{
// Setup the Authentication Token
CrmAuthenticationToken crmAuthenticationToken = new CrmAuthenticationToken
{
OrganizationName = organizationName,
AuthenticationType = 0
};
var crmServiceUriBuilder = new UriBuilder(crmServerUrl) { Path = "//MSCRMServices//2007//CrmService.asmx" };
// Instantiate a CrmService
var crmService = new Microsoft.Crm.SdkTypeProxy.CrmService
{
Url = crmServiceUriBuilder.ToString(),
UseDefaultCredentials = false,
Credentials = networkCredential,
CrmAuthenticationTokenValue = crmAuthenticationToken
};
return crmService;
}
