The Windows operating systems require all users to log on to the computer with a valid account to access local and network resources.
Windows-based computers secure resources by implementing the logon process, in which users are authenticated. After a user is authenticated, authorization and access control technologies implement the second phase of protecting resources: determining if the authenticated user is authorized to access a resource.
The contents of this topic apply to versions of Windows designated in the Applies to list at the beginning of this topic. In addition, applications and services can require users to sign in to access those resources that are offered by the application or service. The sign-in process is similar to the logon process, in that a valid account and correct credentials are required, but logon information is stored in the Security Account Manager SAM database on the local computer and in Active Directory where applicable.
Sign-in account and credential information is managed by the application or service, and optionally can be stored locally in Credential Locker. To understand how authentication works, see Windows Authentication Concepts. The logon process begins either when a user enters credentials in the credentials entry dialog box, or when the user inserts a smart card into the smart card reader, or when the user interacts with a biometric device.
Users can perform an interactive logon by using a local user account or a domain account to log on to a computer. Credentials that the user presents for a domain logon contain all the elements necessary for a local logon, such as account name and password or certificate, and Active Directory domain information.
The process confirms the user's identification to the security database on the user's local computer or to an Active Directory domain. This mandatory logon process cannot be turned off for users in a domain. Locally, when the user has direct physical access to the computer, or when the computer is part of a network of computers.
A local logon grants a user permission to access Windows resources on the local computer. The SAM protects and manages user and group information in the form of security accounts stored in the local computer registry. The computer can have network access, but it is not required. Local user account and group membership information is used to manage access to local resources. A network logon grants a user permission to access Windows resources on the local computer in addition to any resources on networked computers as defined by the credential's access token.
Both a local logon and a network logon require that the user has a user account in the Security Accounts Manager SAM on the local computer. Local user account and group membership information is used to manage access to local resources, and the access token for the user defines what resources can be accessed on networked computers. A local logon and a network logon are not sufficient to grant the user and computer permission to access and to use domain resources. After an interactive logon, Windows runs applications on behalf of the user, and the user can interact with those applications.
Please explain more about this. I do not understand what you mean. Could you post a new question and maybe link it form a comment? I will have a look at it. LogonUserIdentity; and then you can get the information about the user like identity. Please note you need to have HttpContext for these code.
Thanks for your response I tried this but not working.. You mean wrong password input at the Windows Auth dialog? It should not allow you pass authentication. This should work: User.

Although it doesn't direclty answer the question AND actually is a "link-only" question, it really is a good read.
Maybe one could write a proper answer and we accept it? Name; return Ok user ;. Lajos Arpad Javier Flores Javier Flores 4 4 silver badges 6 6 bronze badges. Yo get the Identity of the running process on server? This only works if you use impersonation. See also docs. If you have a reason to do so, then it is correct, but otherwise, you should probably not use impersonation.

No UI is required when using the application. Public client applications should use WAM on Windows. WAM can login the current windows user silently. Federated users only, i. Does not work for MSA users. This one is tricky. IWA is non-interactive, but 2FA requires user interactivity.
