Bug#1400: Cron should respect /etc/group

[Dirk.Eddelbuettel@qed.econ.queensu.ca]

Package: cron
Version: 3.0pl1-18

The following simple script 'fetchmail' runs fine from 'bash' (indented for
this mail as the following paragraphs)
    #!/bin/sh
    (/usr/sbin/dip /usr/local/etc/dip.telnet1  &&  sleep 5s && \
          popclient -3 -P <password-on-pop-server-file> <pop-server> )
    /usr/sbin/dip -k

Unfortunately, it won't run when started by 'cron'. I receive:
    Date: Wed, 20 Sep 95 15:37 EDT
    From: root (Cron Daemon)
    To: edd
    Subject: Cron <edd@miles> ~/bin/fetchmail

    /home/edd/bin/fetchmail: /usr/sbin/dip: Permission denied
    /home/edd/bin/fetchmail: /usr/sbin/dip: Permission denied

'dip' and 'cron' have standard permissions:
    -rwxr-xr-x   1 root     root        24576 Jun 18 20:47 /usr/sbin/cron
    -rwsr-x---   1 root     dip         69632 Aug 22 18:35 /usr/sbin/dip

and 'edd' is part of the 'dip' entry in /etc/group. 'cron' should check this.

The 'fetchmail' script does what it is supposed to do when I change the gid
of edd in /etc/passwd to 30, the value of the dip group.

A 'newgrp dip' in the 'fetchmail' script didn't help either.
