Creating an authenticated ClientContext object is a multistep process. First, the user must be able to sign into the remote system interactively. First, the user signs into SharePoint through the federated authentication provider, and SharePoint must issue its authentication cookies.
To demonstrate the shortcomings of relying solely on Windows authentication, consider an environment that uses only Windows authentication.
What is the status code for classic authentication in SharePoint?
When using classic authentication, you expect that SharePoint will issue an HTTP status code of 401 at the client, indicating the types of HTTP authentication the server supports. However, in claims mode a more complex interaction occurs.
Why are there multiple authentication databases in SharePoint?
Maintaining multiple separate authentication databases became problematic, because users would want to use their same user names and passwords across applications. Creating accounts with the same user name and password is a manageable problem.
Obviously, this is not the best user experience. However, if the same network uses forms-based authentication, after users log in to SharePoint, they are not prompted for authentication in other applications such as Word and Excel. But they are prompted for authentication on each of the two web applications.
Fundamentally, the forms-based mechanism was designed to authenticate against local users, that is, it was not designed to authenticate identity based on a federated system. SharePoint 2010 addressed this by adding direct support for claims-based authentication.
How to use SharePoint’s Client object model with a form?
Using SharePoint’s Client object Model against a SharePoint site that is not using IWA (Kerberos or NTLM) is not supported out of the box (at least not as clean as I would like). If the site is using Forms Based Authentication and you can prompt the user for the user name and password, it can be done by using the following:
How to retrieve data from multi-authentication site using client?
Often you want to retrieve data from such a site by using either the client object model or SharePoint web services, but you want to use Windows authentication to do so. The problem up to this point has always been that even when you set your Windows credentials on the request, you still get an access denied error when requesting the data.
The Kerberos protocol provides mechanisms that enable a user to authenticate against a centralized server and then convey his or her identity through a ticket signed by that server. The advantage of this approach is that the centralized server is the only one that must know the user’s password or other identifying information.
Install online service management tools on a web server in your SharePoint Server farm. Configure server-to-server authentication: Set variables you’ll be using in later steps. Upload the built-in SharePoint Server STS certificate to SharePoint in Microsoft 365. Add a Service Principal Name (SPN) to Azure.
Do you need to enable OAuth in SharePoint Server?
By default, OAuth in SharePoint Server requires HTTPS. If you configured your primary web application to use HTTP instead of SSL, you have to enable OAuth over HTTP on every web server in your SharePoint Server farm.
What kind of authentication is used in SharePoint?
The most popular approach for a shared authentication database is one that uses the Kerberos protocol. The Kerberos protocol provides mechanisms that enable a user to authenticate against a centralized server and then convey his or her identity through a ticket signed by that server.
