Not able to submit cron jobs in AIX

1.     User was not able to submit cron jobs in AIX.

a.       I have resolved this issue as below.

b.       /var/adm/cron/cron.allow  -- to allow user to enable cron job submission.

c.       /var/adm/cron/cron.deny   -- to disallow user to cron job submission.

d.       If you want to enable job submission for user add his user name in cron.allow , to disallow user to cron job submission add his name in cron.deny file. Root can do it.

e.       Both files were ok then what was the issue?

f.       User was not able to add cron entries as it’s “deamon” attribute was set to false.

g.       I have changed it to TRUE.

h.       And User was happy and appreciated me for this.
