Modifier les paramètres SELinux pour permissive a fonctionné pour moi.
Dans Fedora Core et RedHat Enterprise, modifier/etc/selinux/config et vous verrez quelques lignes comme celle-ci:
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
# targeted - Only targeted network daemons are protected.
# strict - Full SELinux protection.
SELINUXTYPE=targeted
... il suffit de changer SELINUX=enforcing
-SELINUX=permissive
et vous avez terminé.
