[Bug 1271538] [NEW] Amavis-Cronjob fails due to problem with SU

[Gunther Stammwitz]

Public bug reported:

Since about two to three days I'm getting errors from an amavis-cronjob.
The error message is: "/usr/sbin/amavisd-new-cronjob: 22: exec: /bin/su: Permission denied".

The cronjob is located in /etc/cron.daily/amavisd-new and contains the following:
"#!/bin/sh
#
#  Daily maintenance for amavisd-new
#  $Id: amavisd-new.cron.daily 930 2006-08-10 13:38:45Z hmh $
#
test -e /usr/sbin/amavisd-new-cronjob && exec /usr/sbin/amavisd-new-cronjob sa-clean
exit 0
"

As one can see the file /usr/sbin/amavisd-new-cronjob is being exectued
with the option sa-clean and line 22 causes the following error: "exec:
/bin/su: Permission denied".

Line 22 looks like this : "exec /bin/su -s /bin/sh - "${SUUSER}" -c "$*" >/dev/null" .
The variable SUUSER is set in line 13: SUUSER="vmail".

To me it looks like vmail is not allowed to run su?
Any idea what has changed?
