Bug 184427

Description of problem:
During boot time, as udev is creating devices, if it comes across a device
without a GROUP= option, it attempts to assign it the group "nogroup".  Normally
this silently fails, as there is no "nogroup" entry in Fedora's stock /etc/group.

However, if in nsswitch.conf, "group" is set to "files ldap", udev will try to
use nss_ldap to contact the LDAP server to resolve "nogroup" to a GID.  Since
udev is started way before the network at boot time, it cannot contact the LDAP
server and you get several errors such as:

vol_id[972]: nss_ldap: failed to bind to LDAP server ldap://servername: Can't
contact LDAP server

Searching Google, I found Mandriva's (and IMO the best) solution was to add a
"nogroup" entry to the stock /etc/group (see link), although hacking udev to use
another default group name, or simply adding a GROUP= option to every record in
/etc/udev/rules.d/* may also fix the problem.

Version-Release number of selected component (if applicable):
FC5test3

How reproducible:
Always

Steps to Reproduce:
1. Add "group = files ldap" to nsswitch.conf
2. Ensure there is no "nogroup" entry in /etc/group
3. Boot the system
  
Actual results:
Lots of nss_ldap errors as example above

Expected results:
udev starts silently and does not require network access.
