I'm sorry, this error is still appearing:

SELinux is preventing ping6 from read access on the chr_file urandom.

*****  Plugin catchall_boolean (47.5 confidence) suggests   ******************

If you want to allow authlogin to nsswitch use ldap
Then you must tell SELinux about this by enabling the 'authlogin_nsswitch_use_ldap' boolean.
You can read 'None' man page for more details.
Do
setsebool -P authlogin_nsswitch_use_ldap 1

*****  Plugin catchall_boolean (47.5 confidence) suggests   ******************

If you want to allow global to ssp
Then you must tell SELinux about this by enabling the 'global_ssp' boolean.
You can read 'None' man page for more details.
Do
setsebool -P global_ssp 1

*****  Plugin catchall (6.38 confidence) suggests   **************************

If you believe that ping6 should be allowed read access on the urandom chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep ping6 /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
