Estou tentando modificar a senha de administrador do LDAP em uma nova instalação do OpenLDAP no CentOS 6.7 (semelhante ao RHEL 6.7).
Eu criei um arquivo chamado change_ldap_password.ldif :
# Hash your password:
# slappasswd -h {SSHA} -s "my_password"
# I also tried {1}hdb instead of {0}config
dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}YP8q2haCD1POSzQC3GAuBdrfaHh+/Y49
Quando executo o seguinte comando como root, recebo um erro de acesso:
# ldapmodify -x -W -D "cn=admin,dc=my_domain,dc=com" -f ./change_ldap_password.ldif
Enter LDAP Password:
modifying entry "olcDatabase={0}config,cn=config"
ldap_modify: Insufficient access (50)
Aqui está a saída do ldapwhoami:
# ldapwhoami -x -W -D "cn=admin,dc=my_domain,dc=com"
Enter LDAP Password:
dn:cn=admin,dc=my_domain,dc=com
Aqui está o resultado do grepping para olcRoot em cn = config:
# grep -R olcRoot /etc/openldap/slapd.d/cn=config
/etc/openldap/slapd.d/cn=config/olcDatabase={1}hdb.ldif:olcRootDN: cn=admin,dc=my_domain,dc=com
/etc/openldap/slapd.d/cn=config/olcDatabase={1}hdb.ldif:olcRootPW:: ...
Aqui estão as informações de depuração para o ldapmodify:
# ldapmodify -x -W -D "cn=admin,dc=my_domain,dc=com" -f ./change_ldap_password.ldif -d1

Se eu digitar uma senha errada, o erro será alterado de Acesso insuficiente a credenciais inválidas:
ldap_bind: Invalid credentials (49)
Eu vi esta pergunta do ServerFault , mas essa era sobre um usuário com um número limitado privilégios em vez de admin ou root.
Como obtenho o erro ldap_modify: Insufficient access (50) ?
Por que o root identificando como administrador LDAP não tem acesso para alterar a senha?
Estou certo de reinstalar o slapd se essa for a solução recomendada. Gostaria de resolver esse erro antes de prosseguir.

Acho que tenho ldapi:// definido em /etc/openldap/ldap.conf , mas não tenho certeza sobre ldapi:///

Edit 2 : Eu recebo o mesmo erro ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1) depois de parar o firewall ( service iptables stop ), então o firewall não é o problema.
