This user right allows a process to impersonate any user without
authentication. The process can therefore gain access to the same
local resources as that user.
Processes that require this privilege should use the LocalSystem
account, which already includes this privilege, rather than using a
separate user account with this privilege specially assigned. If
your organization only uses servers that are members of the Windows
Server 2003 family, you do not need to assign this privilege to your
users. However, if your organization uses servers running Windows
2000 or Windows NT 4.0, you might need to assign this privilege to
use applications that exchange passwords in plaintext.
Caution
Assigning this user right can be a security risk. Only assign this
user right to trusted users.
Default: None.
