Since I like to avoid extra work like that, it looks like LOGON32_LOGON_BATCH or LOGON32_LOGON_INTERACTIVE would both be more appropriate choices. Selecting between them will depend on the rights that the account we're trying to logon has. Once your call to LogonUser has gotten you a user token for the user you'd like to impersonate, you can then call WindowsIdentity.Impersonate() and have your thread take over the identity of the Windows user you just logged on. https://blogs.msdn.microsoft.com/shawnfa/2005/03/21/how-to-impersonate/ !!!!Tips & Tricks: Please add some! !!!!Sample Code: // Call LogonUser to get a token for the user IntPtr userHandle = IntPtr.Zero(); bool loggedOn = LogonUser( user, domain, password, LogonType.Interactive, LogonProvider.Default, out userHandle); if(!loggedOn) throw new Win32Exception(Marshal.GetLastWin32Error()); // Begin impersonating the user WindowsImpersonationContext impersonationContext = WindowsIdentity.Impersonate(userHandle.Token); DoSomeWorkWhileImpersonating(); // Clean up CloseHandle(userHandle); impersonationContext.Undo(); !!!!Alternative Managed API: Do you know one? Please contribute it! Documentation: LOGON_TYPE@msdn on MSDN
