Description of problem:If I leave ldap in nsswitch.conf with the newest versions
of openldap/nscd/nss_ldap and reboot either FC5 or FC6 the system hangs at
'Starting System Message bus'.
Version-Release number of selected component (if applicable):
How reproducible: every time I reboot.
Steps to Reproduce:
1.reboot with nscd set to start on boot.
2.ldap in nsswitch.conf (in any position in the list)
Actual results: system hangs during boot.
Expected results: should get a clean boot.
Additional info:If I remove ldap from nsswitch.conf and reboot the system will
reboot fine, but this is inconvenient since I have a dozen FC boxes that do
occassionally need rebooting. Please let me know what other info I can provide.

Try setting "nss_initgroups_ignoreusers root,nscd" in /etc/ldap.conf. Assuming
it's a problem during group membership enumeration, this should work around it.
Please attach nsswitch.conf for the "hang" case, so that we can be sure you're
not running into a recursion problem in hostname resolution and the like. Thanks!

nsswitch.conf as requested.
It looks as if the command added into ldap.conf fixed the problem. I'm 2 for 2
with it on servers I've rebooted that have had this problem. One FC5 the other
Please add "nscd" to "nss_initgroups_ignoreusers" in default /etc/ldap.conf
It looks like this fixes the problem. In every case I am able to reboot
