CentOS - Jun 2013 - Is there a rpm command to find the package that created a particular user or particular group?

Given a particular user or particular group, is there a rpm command that
returns what package created that particular user or particular group?

Analogous to `rpm -q --whatprovides /etc/security/limits.conf` returns the
package "pam".
Is there an rpm command that returns what package generated a particular
user?

Most of us already know that the httpd package is associated with the user
apache.  But there are passwd and group entries that i would like to verify
and want to know exactly how they got on my system.  Further i would like
to know which the security implications of adding another group to a user
account.

Something like the following command:
`rpm --query --user apache`              would return "httpd"
`rpm --query --group pulse-access`   might return pulseaudio

take a look at the pre/post-script parts of the rpms

rpm -q --scripts httpd

other users/groups are "installed" via centos setup (anaconda).
