It is the first time that I am configuring an openLDAP.
I download these four rpms :
1)openldap-2.3.30-3.fc6.i386.rpm
2)openldap-clients-2.3.30-3.fc6.i386.rpm
3)openldap-devel-2.3.30-3.fc6.i386.rpm
4)openldap-servers-2.3.30-3.fc6.i386.rpm
and used "yum" to install all of them individual.
And change the conf file.
The ldap status is running.
here is my sldap.conf:
  
database	bdb
suffix		"dc=example,dc=com"
rootdn		"cn=Manager,dc=example,dc=com"
rootpw     password
directory	/var/lib/ldap
index objectClass                       eq,pres
index ou,cn,mail,surname,givenname      eq,pres,sub
index uidNumber,gidNumber,loginShell    eq,pres
index uid,memberUid                     eq,pres,sub
index nisMapName,nisMapEntry            eq,pres,sub

and here is my ldif file:
dn: dc=example,dc=com
objectClass:dcobject
objectClass:organization
objectClass:top
dc: example

and ran this command:
  ldappadd -x -D "cn=Manager,dc=example,dc=com" -w password -f test.ldif
and here is the result:
ldap_add:Server is unwilling to perform (53)
        additional info: no global superior knowledge
I add this part to the ldif file:
dn: cn=Manager,dc=example,dc=com
objectClass: organizatiolRole
cn: Manager
 and ran the same command and git the same error.
I tried to use LDAP browser and I am able to connect but can not add any entry.
Could you please let me know what to do and why it happens?
I would really appreciate if someone can help.
Thanks....Homa
