No schema in my db

[Olivier Cailloux <olivier.cailloux@ulb.ac.be>]

Hello,

I'm trying to set up an LDAP server on my box (only for address book 
management). It seems like there is no schema (or a problem related to 
the schema) on my test server, and I don't know what I should do to 
overcome that problem.

The problem (well I think this is a problem) is:
Olivier:/etc/ldap# ldapsearch -b cn=schema -x
# extended LDIF
#
# LDAPv3
# base <cn=schema> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 32 No such object

# numResponses: 1



Here is my slapd.config file:
Olivier:/etc/ldap# grep ^[^#$] slapd.conf
access to dn.base=""
by * read
include         /etc/ldap/schema/core.schema
include         /etc/ldap/schema/cosine.schema

And the contents:

More practically, my problem is that using phpldapadmin, I get a "no 
schema" error after logging in, and I suppose this is related to the "No 
such object" reply here above...

Any help or pointer would be really appreciated, because I'm searching 
since two days!

P.S. : not related, but I was wondering if it is better to create a 
"o=smg" organisation or "dc=smg8,dc=ulb,dc=ac,dc=be" following my dns name?

Thank you.
