Abaixo, mostro minha configuração do OpenLDAP. Esta é uma nova instalação do OpenLDAP em uma nova instalação Debian Stretch.
Eu não consigo usar ldapscripts. Independentemente do que eu faça, recebo os erros mostrados no final do texto abaixo.

/var/log/ldapscripts.log mostra uma reclamação sobre "credenciais inválidas". No entanto, isso acontece se eu colocar minha senha cn = admin real em /etc/ldapscripts/ldapscripts.passwd ou se eu colocar a palavra "secret" nela.

Observe a aparência do meu nome de usuário (my-username) na saída de log acima. Isso ocorre apesar de eu ter executado todos os comandos OpenLDAP após su -l root .
Qual o passo que estou faltando para usar com sucesso ldapscripts?
Respostas:
Teve um problema semelhante, ou seja, o mesmo erro: ldap_bind: Credenciais inválidas (49)
e a única maneira de resolvê-lo era apagar o ldapscripts.passwd e usar
(antes de editar o arquivo diretamente com o vi digitando a senha). HTH.
