Arhhhh....
So that probably would explain why I can no longer log in as root when
the NSS LDAP server is down, even with LDAP PAM support disabled and
files is listed before ldap in /etc/nsswitch.conf.
ethereal shows the following queries when it is working:

The second query is trying to find out all the groups root is in (is
it possible to skip this???).
I don't understand the first one. root is defined in /etc/passwd.
getent passwd with the LDAP server down lists all local users
(including root) before hanging.
