Description of problem:  When switching networks, it seems that NetworkManager
tries to kill (and presumably restart?) all nscd processes, but the selinux
policy prevents it from doing this.  I suspect this may be contributing to the
problems I have with programs (e.g., fetchmail in daemon mode) using stale DNS
information when switching networks.

Version-Release number of selected component (if applicable):
selinux-policy-2.2.23-15
selinux-policy-targeted-2.2.23-15
NetworkManager-0.6.0-3
nscd-2.4-4

How reproducible:  Always, I think.  I saw it in FC4 as well when I tried
running nscd.

Steps to Reproduce:
1. # /sbin/service nscd start (if it's not already running)
2. # tail -f /var/log/audit/audit.log | grep denied
3. switch or re-select a wireless network using the menu on the NetworkManager
GNOME tray icon.
  
Actual results:
type=AVC msg=audit(1142915564.632:866): avc:  denied  { signal } for  pid=28802
comm="killall" scontext=system_u:system_r:NetworkManager_t:s0
tcontext=user_u:system_r:nscd_t:s0 tclass=process

Expected results:
No selinux denials.

Additional info:
I'm not actually sure if I'm *supposed* to be using nscd with NetworkManager,
although the fact that NetworkManager is doing this suggests that I am.
