No Root DSE returned from OpenLDAP

Solution 1:

This is actually filed as bug #427842 agains Ubuntu 9.10 (karmic).

To fix this, copy the following to fixRootDSE.ldif:

dn: olcDatabase={-1}frontend,cn=config
changetype: modify
add: olcAccess
olcAccess: to dn.base="" by * read
olcAccess: to dn.base="cn=subschema" by * read

And execute

sudo ldapmodify -Y EXTERNAL -H ldapi:/// -f fixRootDSE.ldif

This should give anonymous access to the root DSE.

Solution 2:

Isn't the Root DSE supposed to be queried anonymously, before binding as a user? So you shouldn't be using -W or -D at all.

My OpenLDAP server responds to the following:

$ ldapsearch -x -b '' -s base

with

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

#
dn:
objectClass: top
objectClass: OpenLDAProotDSE
