	Privet Dima,

	This is from the man page:
============
     The superuser may use these commands in any case.  For other users,
per-mission to use at is determined by the files /var/at/at.allow and 
/var/at/at.deny.
     If the file /var/at/at.allow exists, only usernames mentioned in it
are allowed to use at.
     If /var/at/at.allow does not exist, /var/at/at.deny is checked, every
username not mentioned in it is then allowed to use at.
=============

	I'd first try doing "touch /var/at/at.allow" which would create an
empty file (hence, no users to allow use of "at" to).
	If the above doesn't work, then you can "cut -f1 -d: /etc/passwd >
/var/at/at.deny", which would then deny use of "at" to all users listed in
/etc/passwd file.
	Oops, just tried first method and I thing you will have to use
the second method:

shell6: {1036} ls -l /var/at/at.deny
-rw-------  1 root  wheel  0 Jul 17  1997 /var/at/at.deny
shell6: {1037} at 10am May 2
ls -l
Job 6 will be executed using /bin/sh
shell6: {1038} atq
Date                    Owner   Queue   Job#
10:00:00 05/02/98       jkb     c       6
shell6: {1039}

	Hope above helps.
