s/Also crontab for root works fine/Also crontab for root works fine in enforcing mode/ Fixed in -41, confirm that everything works fine now. Argh.. closed by mistake. |
Description of problem: With selinux in enforcing mode (policy targeted): [root@localhost ~]# crontab -u adi Access denied by SELinux, must be privileged to use -u [adi@localhost ~]$ crontab -l cron/adi: Brak dostępu (means: no access) After setting selinux into permissive mode, everything works fine, crontab is accessible from user and root accounts. Also crontab for root works fine.
