Tenho o Samba4 rodando no centos 7, tudo normal, gostaria de fazer algumas consultas ldap na base do samba

Tentei
ldapsearch -b "dc=ceivas,dc=local" -h 192.168.0.253 -D "cn=administrator,cn=Users,dc=ceivas,dc=local" -W
Enter LDAP Password:
ldap_bind: Strong(er) authentication required (8)
additional info: BindSimple: Transport encryption required.

Tentei configurar o /etc/openldap/ldap.conf

BASE dc=ceivas,dc=local
#URI ldap://ldap.example.com ldap://ldap-master.example.com:666
URI ldap://localhost:389

#SIZELIMIT 12
#TIMELIMIT 15
#DEREF never

#TLS_CACERTDIR /etc/openldap/certs

# Turning this off breaks GSSAPI used with krb5 when rdns = false
SASL_NOCANON on

Alguém pode me ajudar com este erro ?
