Description of problem:
SELinux is preventing dhclient from 'read' accesses on the chr_file random.

*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************

Sie folgendes tun möchten: allow authlogin to nsswitch use ldap
Then sie müssen SELinux darüber benachrichtigen, indem Sie die 	boolesche Variable »authlogin_nsswitch_use_ldap« aktivieren.

Do
setsebool -P authlogin_nsswitch_use_ldap 1

*****  Plugin catchall (11.6 confidence) suggests   **************************

If you believe that dhclient should be allowed read access on the random chr_file by default.
Then sie sollten dies als Fehler melden.
Um diesen Zugriff zu erlauben, können Sie ein lokales Richtlinien-Modul erstellen.
Do
allow this access for now by executing:
# ausearch -c 'dhclient' --raw | audit2allow -M my-dhclient
# semodule -X 300 -i my-dhclient.pp
