Hi,
Some peculiar problem with FC5 with ldap server installed in it. It is not possible to start the system message bus (SMB). This even happens when authconfig is configured for an LDAP client. The solution (weird, but temporarily works !), was found in found in Fedora Forum :

1. selinux=0 in grub.conf
2. Remove mention of ldap and ldaps in /etc/nsswitch.conf (wierd, in FC4 they are there but named starts fine).
3. Remove the same from /etc/sysconfig/authconfig
3. Sent *.* to /dev/tty12 in /etc/syslog.conf helped debugged the problem

Any more ideas expected !
