alterando senha ldap_bind: Credenciais inválidas (49)

Informação:
Eu instalei ldap-utilse slapd, durante a instalação do slapd, com ncurseso dialog, importei a senha do administrador.
Depois eu alterei via

ldapmodify -Q -Y EXTERNAL -H ldapi:/// << E0F
dn: olcDatabase={1}mdb,cn=config
changetype: modify
replace: olcRootPW
olcRootPW: {SSHA}qUoTRPwppaedqHQTgYOPYWokr3SiXjbK
E0F

Mas ldapadd -x -D "cn=admin,dc=example,dc=com" -W -f ./users.ldifrecebo as seguintes mensagens:

Enter LDAP Password: 
ldap_bind: Invalid credentials (49)

A propósito, eu não tenho slapd.conf.
Como posso autenticar via programas ldap?
