Description of problem:
SELinux is preventing pptpcm from 'open' 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.
You can read 'None' man page for more details.
Do
setsebool -P authlogin_nsswitch_use_ldap 1

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

If you believe that pptpcm should be allowed open 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 'pptpcm' --raw | audit2allow -M my-pptpcm
# semodule -X 300 -i my-pptpcm.pp
