Description Robert Dale 2019-03-11 16:18:55 UTC
Description of problem:
Using NetworkManager VPN and Sonicwall NetExtender VPN 
SELinux is preventing ip from 'read' accesses on the chr_file /dev/random.

*****  Plugin catchall_boolean (89.3 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.

Do
setsebool -P authlogin_nsswitch_use_ldap 1

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

If you believe that ip should be allowed read access on the random 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:
# ausearch -c 'ip' --raw | audit2allow -M my-ip
# semodule -X 300 -i my-ip.pp
