Attach your /etc/ldap.conf file. Misconfiguration there (especially removing the nss_initgroups_ignoreusers line) can easily cause timeouts as nss attempts to get user and group information before the network or LDAP server are started. Created attachment 144672 [details]
ldap.conf file of one machine that hangs on reboot.
This is a copy of the ldap.conf file you requested. I've used this same
configuration for over a year now and until the upgrades to FC5 and 6 have seen
no problems at all.
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! Created attachment 144702 [details]
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
FC6.
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 successfully.
