crontab_setgid: you're not in /etc/cron.allow

[DevSysEngineer]

Hello,

I am trying to install Naemon, which includes Thruk. Unfortunately, the installation of Thruk keeps failing. Please see error log.

Thruk have been configured for xxxxxx.
The default user is 'thrukadmin' with password 'thrukadmin'. You can usually change that by 'htpasswd /etc/thruk/htpasswd thrukadmin'
[ERROR] cron_post_edit_cmd (/usr/bin/crontab /var/cache/thruk/thruk_cron.tmp && rm -f /var/cache/thruk/thruk_cron.tmp 2>>/var/lib/thruk/cron.log) exited with value 1: crontab_setgid: you're not in /etc/cron.allow

Thruk wants to create crontab entries. If you have some hardened linux, you need to make sure the thruk user (ex. apache) is allowed to do so.
