rpm -qf saying file doesnot belong to any package ??

Is there a way to find package names using some other rpm switch when -qf doesnot work ? for example linux:~ # rpm -qf /etc/sysconfig/security file /etc/sysconfig/security is not owned by any package or ,when i run linux:~ #rpm -qaV |grep '/etc/sysconfig' S.5....T c /etc/sysconfig/network/config .......T /etc/sysconfig/network/ifcfg.template .......T c /etc/sysconfig/network/ifroute-lo I have made changes in the /etc/sysconfig /security file but nothing shows here ,how do i know which rpm it belongs to , it came with the install, I did not create it.
