Warning: Invalid Account: %s is not allowed to execute cronjobs
on Solaris 10+
This can mean that this account is not in /etc/cron.d/cron.allow or at.allow.
In my case, it didn't. It meant that I was trying to use an account with /etc/shadow's entry set to *LK* to run a cronjob.
How you fix this depends on what you want done. You can change *LK* to something else, like ! or NP, or give it a password.
