"I have no name!" -- for root???

["Ken D'Ambrosio" <kend@xanoptix.com>]

Hello, all.  I noticed some network flakiness, and went to check on it 
by ssh'ing into my main server (which queries another box running 
slapd).  When I logged in -- as root! -- I was informed

I have no name!@nebula:/etc/ldap#

I wouldn't even be sending this to the OpenLDAP list, except that when I 
plugged it in to Google, it seemed LDAP-related.  What I'm really 
confused about, however, is that root, obviously, is a local account.  
This machine has worked fine for months, and while one of my LDAP 
servers may have had a hiccough, I don't really see why that would 
influence the local account.  My /etc/nsswitch.conf queries files first 
(and LDAP as the only other entry), so I'm just plain puzzled.  To top 
it all off, when I did an "lsof", I was informed:

lsof: no pwd entry for UID 0

Any ideas on what might be wrong?  Is it LDAP-related, or no?  I do have 
nscd running; any chance that that could become confused if it can't 
talk to an LDAP server?

Thanks much,
