WindowsIdentity Constructor (String, String)
Initializes a new instance of the WindowsIdentity class for the user represented by the specified User Principal Name (UPN) and the specified authentication type.
Assembly: mscorlib (in mscorlib.dll)
Windows returned the Windows NT status code STATUS_ACCESS_DENIED.
There is insufficient memory available.
The caller does not have the correct permissions.
The computer is not attached to a Windows 2003 or later domain.
The computer is not running Windows 2003 or later.
The user is not a member of the domain the computer is attached to.
The value of the type parameter is used to set the AuthenticationType parameter. If type is null, the security system sets AuthenticationType to Negotiate on Windows Vista and later versions of the Windows operating system, and to Kerberos on earlier versions of the Windows operating system. The security system does not use this value; it is for informational use only.
The UPN identified in sUserPrincipalName is used to retrieve a token for that user through the Win32 API LsaLogonUser function. In turn that token is used to identify the user. An exception might be returned due to the inability to log on using the supplied UPN.
This constructor is intended for use only on computers joined to Windows Server 2003 domains. An exception is thrown for other domain types. This restriction is because the constructor uses the KERB_S4U_LOGON structure.
