   sudo is more like the runas feature present in Windows 2000.  See =
"Use Run As to Start Administrative Tools While Logged On as a
User" =

px or =
http://www.microsoft.com/windows/windows2000/en/advanced/help/runas.htm. =
 This is what sudo claims to do at http://www.sudo.ws/sudo/man/sudo.html =
which states "sudo allows a permitted user to execute a command as the
= superuser or another user".

   UAC is something much more interesting.  A notable difference is that =
for a user that is an administrator the elevated process doesn't run as =
another user.  It runs as the same user with the same identity but =
elevated privileges.  And this is only one aspect of UAC.

  Did Microsoft just patent sudo?

  Holy crap, I think they did. Here's the patent for UAC:=20

  >>
  A computer such as a network appliance executes an administrative
  security process configured to run under an administrative privilege
  level. Having an administrative privilege level, the administrative
  security process can initiate administrative functions in an operating
  system function library. A user process executing under a
  non-administrative privilege level can initiate a particular
  administrative function that the process would not otherwise be able =
to
  initiate by requesting that the administrative security process =
initiate
  the function. In response to a request to initiate a particular =
function
  from a process with a non-administrative privilege level, the
  administrative security process determines whether the requesting
  process is authorized to initiate the particular administrative =
function
  based on information accessed in a data store. If the requesting =
process
  is authorized, the administrative security process initiates the
  particular administrative function. In this manner, the administrative
  security process facilitates access to specific administrative =
functions
  for a user process having a privilege level that does not permit the
  user process to access the administrative functions.

  Does that sound like sudo to you? Does to me. If you look at sudo's
  manpage, you'll find a link to this site: The History of Sudo.=20
  http://www.sudo.ws/sudo/history.html
  What can this site tell us? Plenty. For instance,

  >>=20
  Sudo was first conceived and implemented by Bob Coggeshall and Cliff
  Spencer around 1980 at the Department of Computer Science at
  SUNY/Buffalo. It ran on a VAX-11/750 running 4.1BSD. An updated =
version,
  credited to Phil Betchel, Cliff Spencer, Gretchen Phillips, John =
LoVerso
  and Don Gworek, was posted to the net.sources newsgroup in December of
  1985.

  1985, huh? And when did this Microsoft patent happen? It was filed in
  2000. Well gee, that doesn't make sense. How'd they get the patent? It
  certainly falls under the category of "obvious" if there's prior art
  such as sudo.

  What makes this whole thing funny, though, is something I saw a couple
  days ago. Head over to Builder-AU and listen to Peter Watson from
  Microsoft. He says,=20

  >>
  User Account Control is a great idea and strategically a direction =
that
  sort of all operating systems and all technology should be heading =
down
  >>

  Excuse me? Does he really believe this is all Microsoft's great new
  idea?

  In the end, this seems like a patent that Microsoft will hold up and =
say
  "we have a patent and Linux is violating it!" They won't ever sue on =
it
  though (just leave the threat hanging to scare away potential users),
  because then they could have the patent revoked. It's better for them =
to
  just wave it around.
