Bug 445667

Description of problem:
Eiciel's display has a checkbox labeled "Also show system participants". This
button is designed to show accounts that do not correspond to people, e.g.,
root, mysql, and so forth. This condition applies where UID<1000, but on a
Fedora system, this should be UID<500 because /etc/libuser.conf leaves
LU_UIDNUMBER at the default value of 500.

The impact of this bug is that the first 500 real users on the system do not
appear in Eiciel's display (which means that on many systems, only nfsnobody is
shown). Selecting the "Also show system participants" shows these real users but
also shows all of the systems accounts (which, on a personal system, will often
be more numerous than the real accounts).

Version-Release number of selected component (if applicable):
eiciel-0.9.5-1.fc8 and eiciel-0.9.5-1.fc9

Steps to Reproduce:
1. Start eiciel with a file argument: /usr/bin/eiciel /etc/services

Actual results:
User accounts where (UID>=500 && UID<1000) are not displayed unless the "Also
show system participants" checkbox is selected.


Expected results:
User accounts where UID>=500 are always shown regardless of the state of the
checkbox. (Ideally, nfsnobody should be suppressed unless the checkbox is
selected too).

Additional info:
The lower limit for the non-system UID should not be hardcoded, but retrieved
from libuser.
