:SELinux is preventing /usr/bin/python2.7 from using the 'sys_nice' capabilities.
:
:*****  Plugin catchall (100. confidence) suggests  ***************************
:
:If you believe that python2.7 should have the sys_nice capability 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 system-config-s /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Installed latest Samba to share files between my Windows 7 box.

Installed system-config-samba
Opened system-config-samba and go the error from SELinux; seems python2.7 need read access to the /var/tmp directory.

Said i should submit bug report so I did for the community.

Comment 8 BLS 2012-10-23 23:25:59 UTC
Installed latest Samba version to share files between Fedora and my Windows box.

Installed system-config-samba
opened system-config-samba

Got the error notice from SELinux and manually enabled the 'sys_nice' function from the output from SELinux troubleshooter.

Not sure if python 2.7 should have access to this function or not but only popped up when I opened system-config-samba (GUI for Samba)

OS Release: Fedora release 17 (Beefy Miracle)
