Hi, a 5.1 desktop box that is LDAPized boots fine here (using remote
LDAP servers, not a local slapd). My guess is that your /etc/ldap.conf
doesn't contain the following line (wrapped for purposes of mail) and
that network/slapd isn't available by the time dbus starts:

nss_initgroups_ignoreusers
root,ldap,named,avahi,haldaemon,dbus,radvd,tomcat,radiusd,news,mailman

That line tells NSS not to ask LDAP for any information concerning the
listed users, including the user that the dbus ("messagebus") runs under.

Hope this helps,
