You want to logoff the user 'john'.
Code:
# w
  11:57AM   up 46 days,  18:02,  2 users,  load average: 1.01, 1.06, 1.06
User     tty          login@       idle      JCPU      PCPU what
john  pts/0       12:40PM       4:38         0         0 rlogin
bob   pts/1       11:57AM          0         0         0 /usr/bin/w64

You must kill the process of his shell. Every user logs into some kind of shell. In the below example john's shell is seen as '-ksh'. That is the process you need to kill.

Code:
# ps -ef|grep john
 john 290912 385216   0 12:40:44  pts/0  0:00 rlogin somenode
 john 323806 569424   0 12:40:35  pts/0  0:00 -ksh

We see the process id, or PID, is 323806. We pass that number to the 'kill' command with a signal of '-9' or TERMINATE.

Code:
# kill -9 323806

And he should be gone. Also consider the fact that whatever they are working on when you do this is lost if they have not saved their work.

I recommend you get your system admin to do this.

kill(1) 						      General Commands Manual							   kill(1)

Name
       kill - send a signal to a process

Syntax
       kill [-sig] processid...
       kill -l

Description
       The command sends the TERM (terminate, 15) signal to the specified processes.  If a signal name or number preceded by `-' is given as first
       argument, that signal is sent instead of terminate.  For further information, see

       The terminate signal kills processes that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot  be  caught.
       By convention, if process number 0 is specified, all members in the process group (that is, processes resulting from the current login) are
       signaled.  This works only if you use and not if you use To kill a process it must either belong to you or you must be superuser.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be  found  by  using	It
       allows job specifiers ``%...''  so process ID's are not as often used as arguments.  See for details.

Options
       -l   Lists  signal  names.  The signal names are listed by `kill -l', and are as given in /usr/include/signal.h, stripped of the common SIG
	    prefix.
