/etc/cron.d not executing RHEL 5

[Allblack]

Haven't posted here for years but I need some help.

I have setup some RHEL5 servers and I need to run some cron jobs.
We need to place entries in /etc/crontab.d but for some reason they do not get executed. We place a file with crontab entry in this directory. An example of such entry would be

0-59/20 * * * * /usr/local/net.support/dhcp/cron.5min

The permissions on /etc/cron.d are chmod 600 and root owned.
The script it point to is set executable and owned by root.
None of the scripts work when ran from /etc/cron.d

Any ideas?

fixed!

You need to specify the user in the entry when working from /etc/cron.d

WOW. For such an old thread this pointed me to the answer.

I SPENT ALL DAY TRYING TO MAKE A /ETC/CRON.D SCRIPT WORK!!!!

Must specify valid user:
* * * * * root echo This works

like this redhat bug (don't know where the upstream bugzilla is).
