I'm using an Windows Azure Cloud Service and when I access to it using my domain name instead of [CLOUDSERVICENAME].cloudapp.net I have problems with authentication cookies.
I'm creating the cookies
FormsAuthenticationTicket authTicket = new FormsAuthenticationTicket(
1,
serializeModel.Username,
DateTime.Now,
DateTime.Now.AddMinutes(15),
false,
userData);
string encTicket = FormsAuthentication.Encrypt(authTicket);
System.Web.HttpCookie faCookie = new System.Web.HttpCookie(FormsAuthentication.FormsCookieName, encTicket);
Response.Cookies.Add(faCookie);
But when I try to decrypt it I get a null value.
HttpCookie authCookie = Request.Cookies[FormsAuthentication.FormsCookieName];
if (authCookie != null)
{
FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(authCookie.Value);
JavaScriptSerializer serializer = new JavaScriptSerializer();
if (!String.IsNullOrEmpty(authTicket.UserData))
{
This is strange since this only happens using my domain name to access it.
I've found that when I use my custom domain (running under a SSL Certificate) the cookie size increase. I believe that this is related with certificate encryption.
To solve this I have to remove some parameters from cookie userdata to guarantee that it doesn't grow to more than 4096 bytes (Browser Cookie Limits: http://browsercookielimits.x64.me/)

I am trying to call MSCRM 365 web services using SOAPUI, this is what i have done so far
Downloaded Organization WSDL from my cRM instance
Uploaded in SOAPUI
Added three header parameters - Content-Type, SOAPAction and Accept
Added Username and Password in Request Properties
Whenever I send a request to MSCRM, I get "HTTP ERROR 401 - Unauthorized: Access is denied"
Anyone have any ideas?
Thanks,
Nitesh
Since this is Dynamics 365 it does not authenticate using Username / Password. Instead you will need to use OAuth as shown in the link
https://msdn.microsoft.com/en-us/library/gg327838.aspx
// TODO Substitute your correct CRM root service address,
string resource = "https://mydomain.crm.dynamics.com";
// TODO Substitute your app registration values that can be obtained after you
// register the app in Active Directory on the Microsoft Azure portal.
string clientId = "e5cf0024-a66a-4f16-85ce-99ba97a24bb2";
string redirectUrl = "http://localhost/SdkSample";
// Authenticate the registered application with Azure Active Directory.
AuthenticationContext authContext =
new AuthenticationContext("https://login.windows.net/common", false);
AuthenticationResult result = authContext.AcquireToken(resource, clientId, new
Uri(redirectUrl));
Use the access token in message requests:
using (HttpClient httpClient = new HttpClient())
{
httpClient.Timeout = new TimeSpan(0, 2, 0); // 2 minutes
httpClient.DefaultRequestHeaders.Authorization =
new AuthenticationHeaderValue("Bearer", result.AccessToken);
Another options would be to shift from Xrm.Client to Xrm.Tools.Connection. See the example in this site.

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" +
"LineofBusiness: " +
c.LineofBusiness);
}
}
//</snippetAuthenticateWithNoHelp3>
}
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.
I have an ASP.NET Identity site and a ASP.NET OData site.
Both sites have CORS enabled and both site are using ASP.NET Identity CookieAuthentication.
When I execute both sites locally on my computer using IIS (not express) the AUTH cookie is being passed in the header on each request to the OData site.
But when I deploy the sites to the production IIS server then the header is missing the AUTH cookie when calling the production OData site.
Both production and my local IIS have the same domain name and CORS is setup to allow all.
The WebApiConfig has
cors = new Http.Cors.EnableCorsAttribute("*", "*", "*");
config.Enable(cors);
Before anyone asks, yes the machine key is the same between sites.
UPDATE
This seems to be a CORS issue.
When both sites are on my local machine they use the same host name and domain name but when the site are on the production server they have different host names and the same domain name.
You might need to specify the "Access-Control-Allow-Origin" inside your OAuthAuthorizationServerProvider.
I'm using OWIN but you should be able to do something similarly.
context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
try adding the policy in your OWIN startup class as below. Just keep in mind that the Startup class might have some different class files since it's a partial class. Also, check ConfigureAuth method to see if everything is set according to your needs there. For instance, you set the external signin cookie of Identity as copied below in ConfigureAuth method to allow External Signin Cookeies like facebook and google.
public void Configuration(IAppBuilder app)
{
//
app.UseCors(CorsOptions.AllowAll);
ConfigureAuth(app);
}
app.UseExternalSignInCookie(Microsoft.AspNet.Identity.DefaultAuthenticationTypes.ExternalCookie);
I finally got this to work.
In the ASP.NET Identity site I have the following:
// configure OAuth for login
app.UseCookieAuthentication(new CookieAuthenticationOptions {
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
Provider = new CookieAuthenticationProvider(),
LoginPath = new PathString("/Account/Login.aspx"),
CookieName = ".TESTAUTH",
CookieDomain = ".test.com",
CookieSecure = CookieSecureOption.Always
});
It seems that the important part on the ASP.NET Identity site is that the "CookieName, CookieDomain, and the Machine Key" must match the one on the OData site.
And then on the OData site I have the following:
// configure OAuth for login
app.UseCookieAuthentication(new CookieAuthenticationOptions {
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
Provider = new CookieAuthenticationProvider { OnApplyRedirect = ApplyRedirect },
LoginPath = new PathString("/Account/Login.aspx"),
CookieName = ".TESTAUTH",
CookieDomain = ".test.com",
CookieSecure = CookieSecureOption.Always
});
// build the configuration for web api
HttpConfiguration config = new HttpConfiguration();
// Enable CORS (Cross-Origin Resource Sharing) for JavaScript / AJAX calls
// NOTE: USING ALL "*" IS NOT RECOMMENDED
var cors = new Http.Cors.EnableCorsAttribute("*", "*", "*");
config.EnableCors(cors);
// call the web api startup
WebApiConfig.Register(config);
app.UseWebApi(config);
private void ApplyRedirect(CookieApplyRedirectContext context)
{
Uri absoluteUri = null;
if (Uri.TryCreate(context.RedirectUri, UriKind.Absolute, absoluteUri))
{
var path = PathString.FromUriComponent(absoluteUri);
if (path == context.OwinContext.Request.PathBase + context.Options.LoginPath)
{
QueryString returnURI = new QueryString(context.Options.ReturnUrlParameter, context.Request.Uri.AbsoluteUri);
context.RedirectUri = "https://www.test.com/Account/Login.aspx" + returnURI.ToString;
}
}
context.Response.Redirect(context.RedirectUri);
}
The "LoginPath" is required even though it does not exist on the OData site and you can't use a full url to another site for the login path.
I used "OnApplyRedirect" to redirect to the actual Login page.
I'm not sure what the difference is between "config.EnableCors" and "app.UseCors" but the EnableCors seems to be working for now.
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.
For one of our FBA enabled SharePoint site, we need to access various web services. I know that we need to invoke Authentication.asmx before we make any other SP web service call.
How do I get the currently logged in user's username & password to pass to the Authentication.asmx service?
Thanks.
Update: I tried Marek's solution with a known username and password and got a 401 for Authentication.asmx. So probably some settings are off. The admin is looking into it.
MembershipUser user = Membership.GetUser();
string username = user.UserName;
string password = user.GetPassword();
Authentication auth = new Authentication();
auth.CookieContainer = new CookieContainer();
LoginResult result = auth.Login(username, password);
if (result.ErrorCode == LoginErrorCode.NoError)
{
CookieCollection cookies = auth.CookieContainer.GetCookies(new Uri(auth.Url));
Cookie authCookie = cookies[result.CookieName];
Lists lists = new Lists();
lists.CookieContainer = new CookieContainer();
lists.CookieContainer.Add(authCookie);
lists.GetListCollection();
}
However, depending on the settings of the membership provider (is password stored in plain text, encrypted or hashed? is it required to pass the security answer to get the password?) retrieving the password may be more difficult or even impossible and you will need to ask the user for it.
