I've been asked to setup a multimaster LDAP environment on Ubuntu 11.04 - instead of a single master server. I cloned the master server and recreated it into two VMs. I am trying to follow the instructions on the OpenLDAP documentation here:

and it talks about modifying the cn=config tree within LDAP. The subdirectory tree appears to be there at:


and a

slapcat -b cn=config

drops out a load of config information. When I try to connect using a browser and the admin bind credentials:

ldapsearch -D '<adminDN>' -w <password> -b 'cn=config'

I get:

# extended LDIF
# LDAPv3
# base <> (default) with scope subtree
# filter: (objectclass=*)
# requesting: ALL

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

I don't see the config context when I connect via an LDAP browser either. I'm sure I'm missing something, but I can't see what it is!

I believe you're using the wrong admin credentials.

Rather certain Ubuntu is setup to use root over SASL/EXTERNAL Unix Sockets as rootDN by default.

# {0}config, config  
dn: olcDatabase={0}config,cn=config  
olcRootDN: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth`

Try using sudo ldapsearch -H ldapi:/// -Y external -b cn=config

Use your old slapd.conf if you have one or copy the one out of /usr/share/doc. If you've got your slapd.conf you can delete the slapd.d/* data and create a new slapd.d configuration from your slapd.conf with

slapadd -f slapd.conf -F slapd.d -n0

be sure to test your configuration with

slaptest -f slapd.conf

and be sure to own everything in slapd.d to openldap or any special ldap-user. OpenLDAP does not provide any slapd.conf file in the default installation. You could do everything with ldapmodify in "live"-Mode, but to provide the first-time-configuration you should use a slapd.conf and convert it.
