Probable newb problem

[Matt Savigear <matt@savigear.com>]

Folks,

I've just upgraded my OpenLDAP server (running on a Gentoo machine) to
version 2.1.23 and managed to bork it, however I'm not sure how. I'm
just using it as a contacts database rather than for anything complex,
so it's pretty much full of inetOrgPerson structures except for one
organization record at the top. 

I've had a hunt round on the list archives, but I can't seem to narrow
the search down to anything which describes the problem correctly. I
haven't changed the configuration between versions, and it all used to
work fine. I have tried changing the permissions on the db directory to
ensure there wasn't a basic permissions issue cropping up.

The symptoms:
* slapcat still successfully shows the content of my database, so
  it's all still intact and accessible.
* Evolution gives me a "the query did not complete successfully" 
  on address lookups.
* ldapsearch returns:

	ldap_initialize( <DEFAULT> )
	Enter LDAP Password:
	filter: (objectclass=*)
	requesting: ALL
	# extended LDIF
	#
	# LDAPv3
	# base <dc=savigear,dc=com> with scope sub
	# filter: (objectclass=*)
	# requesting: ALL
	#
	
	# search result
	search: 2
	result: 32 No such object
	
	# numResponses: 1


Here is my slapd.conf (edited for comments):
----------------------------------------------------------------
include         /etc/openldap/schema/core.schema
include         /etc/openldap/schema/cosine.schema
include         /etc/openldap/schema/inetorgperson.schema

pidfile         /var/run/openldap/slapd.pid
argsfile        /var/run/openldap/slapd.args

database        ldbm
suffix          "dc=savigear,dc=com"
rootdn          "cn=rootlogin,dc=savigear,dc=com"
rootpw          insertpasswordhere

directory       /var/lib/openldap-ldbm

index   objectClass     eq
----------------------------------------------------------------


I realise this first mail is light on detail - I;m hoping that someone
might be able to tell me what else I need to include in order for
someone to assist.

Thanks in advance for any help,

Matt.
