SELinux is preventing /usr/sbin/pptp from 'read' accesses on the file unix.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that pptp should be allowed read access on the unix 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 pptp /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
