Set SE troubleshootd says to run:
$ restorecon -v '/usr/sbin/pppd'
I've tried but no hope. Same error.
Here below is the detailed SElinux error:
--- [snip] ---
*Summary*
SELinux is preventing ifup-ppp (usernetctl_t) "getattr" to /usr/sbin/pppd (pppd_exec_t).
*Detailed Description*
SELinux denied access requested by ifup-ppp. It is not expected that this access is required by ifup-ppp and this access may signal an intrusion attempt. It is also possible that the specific version or configuration of the application is causing it to require additional access.
*Allowing Access*
Sometimes labeling problems can cause SELinux denials. You could try to restore the default system file context for /usr/sbin/pppd,
restorecon -v '/usr/sbin/pppd'
If this does not work, there is currently no automatic way to allow this access. Instead, you can generate a local policy module to allow this access - see FAQ Or you can disable SELinux protection altogether. Disabling SELinux protection is not recommended. Please file a bug report against this package.

Run the troubleshooter with 'sealert -b'. You'll see the same error messageOn Sunday 25 May 2008 15:49:28 Marco Guazzone wrote:
