Thanks much Steve for your details. Yes the user tomcat didn't have a password set. Thanks KK -----Original Message----- From: redhat-list-bounces@xxxxxxxxxx [mailto:redhat-list-bounces@xxxxxxxxxx] On Behalf Of Steve Phillips Sent: Tuesday, August 04, 2009 8:27 PM To: General Red Hat Linux discussion list Subject: Re: Cron not working You will probably find that the tomcat user account is locked in the shadow file (not having a valid password). Locked accounts tend to be limited in what resources they can consume, cron being one of them - this is defined with pam and the configuration file is found in /etc/pam.d/cron - part of this config checks that the account is valid (password not expired etc) and the access.conf file is also checked for overrides - hence why adding the timcat user to access.conf allowed cron to work. man 8 pam man access.conf man pam_access for more information. Also, it is unwise to tinker with these settings (pam configs) on a production box as incorrectly setting pam modules can either render your system un-usable or allow someone to bypass security and gain unauthorized access to your system.
