In this tip, we are going to look at how to invoke WebAPI that has basic or Windows authentication enabled. Authentication information is sent as part of request header in case of basic authentication. Credentials are base64 encoded not encrypted.
It is relatively simple and supported by all major browsers. This authentication is also vulnerable to CSRF cross-site request forgery attacks. Once the credentials are entered, the browser automatically sends them on subsequent requests to the same domain, for the duration of the session. Once logged in, there is no way to logout. If you want to logout, you have to end the session.
Credentials are sent in authorization header. Intranet applications are the best places to use this authentication. This is not a recommended way to authenticate internet applications and vulnerable to CSRF attacks. Message handlers are used for setting Windows authentication details. So what is a message handler? On the client side, the HttpClient class uses a message handler to process requests. The default handler is HttpClientHandlerwhich sends the request over the network and gets the response from the server.
This class is the default message handler for HttpClient. This class, and classes derived from it, enable us to configure a variety of options on an HTTP request like proxies and authentication. Even though this is the default message handler, in order to set authentication and other properties, an explicit object has to be created and passed on to HttpClient.
The code below shows how to use Windows authentication using this class. This class is under System. Http DLL. It is included in System. This also requires an object to be created for setting the required properties and passed to HttpClient. The below code shows how to set Windows authentication.Posted 19 Jul Link to this post.

I am able to install npm packages using Fiddler as the proxy, but it doesn't work for either VS Code extensions or Atom packages. I have the "Automatically Authenticate" rule enabled. The proxy server responds with a again and in the response body it says "Cache Access Denied.

So my question is: Can I force Fiddler to use Kerberos authentication? Also what I don't understand is why npm can install packages but apm Atom package manager can't. When I install a npm package, I only see http tunnels to registry.

Thanks Martina but i would like to ask 2 questions i appropriate if any one has information Can you please suggest the steps, while doing the DB Refreshes. What are the table we need to take backup.
It is very hard to doing the steps again. Please check the first 2 videos of this page. I understand that the intention of this is that it will also work on browser-based applications.
Can please someone advise what I might be missing? I did follow the instructions in the first video. If your users have different user names in various backend systems, you need a system-specific user mapping.

On some less common OS - browser combinations, you may need to use the fully qualified domain name. The first line allows Kerberos authentication to servers on the corporate network. The last line enables forwarding the authentication. That works like agent forwarding. It's optional. You need an admininstrative Active Directory user account. All commands must be executed as root on the server. Install Kerberos utilities with apt-get install krb5-user.

Install msktutil. If you're running jessie testing at the time of writingall you need is apt-get install msktutil. If you're running wheezy stable at the time of writingyou have to download a releasefix a broken dependency declaration click "view source" before copy-pasting the scriptinstall the package with dpkg -i msktutil.
Depending on your requirements, you may be able to perform the next steps with fewer commands. Check your DNS setup. Your server's FQDN server. This confirms that Kerberos works and authenticates you for the next step. Run msktutil --create --verbose shorter version: msktutil -c. Running in verbose mode tells you exactly what msktutil does. This enables daily execution of msktutil --auto-updatewhich prevents the account from expiring as long as the server is alive and updates the keytab when necessary.
At this point, assuming your workstation is set up properly see aboveyou have a user account on the server, and you're always using the same username, you should be able to log in to the server simply with ssh server. If you're using a different name for the service, service. This helps users who are running Windows but aren't in the domain.
Warning: the user credentials will be sent in clear! COM rather than just firstname. At this point, assuming your workstation is set up properly see above and the application supports remote authentication, you should be automatically logged in.

When you try to call a Web service application and Anonymous access authentication is turned off, you may receive the following error message. Description: An unhandled exception occurred during the execution of the current Web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System. When Anonymous access authentication is turned off for the Web service application, all the caller applications must provide the credentials before making any request.
By default, the Web service client proxy does not inherit the credentials of the security context where the Web service client application is running. To resolve this problem, you must use the Credentials property of the Web service client proxy to set the security credentials for Web service client authentication.
To set the Credentials property, do one of the following: First Method Assign the DefaultCredentials to the Credentials property of the Web Service Proxy class to call the Web service while Anonymous access authentication is turned off. The DefaultCredentials property of the CredentialCache class provides system credentials of the security context where the application is running. To do this, use the following code: Visual C. Add new Uri myProxy. Add New Uri myProxy.
This behavior is by design. More Information. DefaultCredentials represents the system credentials for the current security context where the application is running. For a client-side application, the default credentials are typically the Windows credentials such as user name, password, and domain of the user who is running the program. For ASP. NET worker process, or the user who is being impersonated. In the following sample ASP.

Cross-platform authentication is achieved by emulating the negotiate behavior of native Windows-to-Windows authentication services that use the Kerberos protocol. In order for cross-platform authentication to work, non-Windows servers in this case, WebLogic Server need to parse SPNEGO tokens in order to extract Kerberos tokens which are then used for authentication. Fully-configured Active Directory authentication service. Specific Active Directory requirements include:.
WebLogic Server installed and configured properly to authenticate through Kerberos, as described in this chapter. Clients must be logged on to a Windows domain and have Kerberos credentials acquired from the Active Directory server in the domain.Creating a UWP Console App
Local logins will not work. These procedures are detailed in the sections that follow. The Kerberos protocol uses the Active Directory server in the Microsoft domain to store the necessary security information. Any Microsoft client you want to access in the Microsoft domain must be set up to use Windows Integrated authentication, sending a Kerberos ticket when available.
The Web application or Web service used in SSO needs to have authentication set in a specific manner. Configure your network domain to use Kerberos. Choose a Microsoft client either a Web service or a browser and configure it to use Windows Integrated authentication. Start WebLogic Server using specific start-up arguments. On any domain controller, the Active Directory and the Kerberos services are running automatically.
Java GSS requires a Kerberos configuration file. The default name and location of the Kerberos configuration file depends on the operating system being used. Java GSS uses the following order to search for the default configuration file:. To configure Kerberos in your Windows domain controller, you need to configure each machine that will access the KDC to locate the Kerberos realm and available KDC servers.
For example:. Example Sample krb5.
