Description Brian Beaudoin 2008-02-11 14:49:03 EST
Description of problem:

The NetworkManager service does not configure devices with "NM_CONTROLLED=yes"
in /etc/sysconfig/network-scripts/ifcfg-eth0 until after GUI authentication has
occurred (regardless of whether the "ONBOOT" variable is set to "yes").  This
prevents network-based authentication (NIS, LDAP, Kerberos, AD) from succeeding.    

Affected Version:  NetworkManager 0.7.0-0.6.7.svn3235.fc8

How reproducible:  Always reproducable with "ONBOOT=yes" and "NM_CONTROLLED=yes"
set in /etc/sysconfig/network-scripts.
  
Actual results:

By default, the "network" service is disabled in Fedora 8 and startup services
such as NTP and Winbind fail prior to NetworkManager starting.  The ethernet
device and "Winbind" can be manually restarted from the console to re-enable
network authentication.

Upon exiting the X Window System, the ethernet device is disabled again.  This
requires "network" and "winbind" to be restarted again before the next user can
log into the system.

Expected results:

NetworkManager should start prior to any network service.  If "ONBOOT=yes" and
"NC_CONTROLLED=yes" then the network should be enabled regardless of the GUI
login state.  When the user exits the session, networking should remain enabled
so the next user can log onto the system using network authentication.

Additional info:

Evolution and Pidgin are linked with NetworkManager and report the network is
unavailable when "NM_CONTROLLED=no" and the "network" service is started at
boot.  My company uses Kerberos 5 to authenticate users and Winbind to get user
information via Active Directory though all forms of network authentication are
affected by the lack of networking during interactive login.

Latest rawhide and F8-updates-testing builds have the system settings service
enabled, which fixes this issue.
