下面，我展示了我的 OpenLDAP 配置。这是在全新 Debian Stretch 安装上全新安装的 OpenLDAP。
我无法使用 ldapscripts。无论我做什么，我都会收到下面文本末尾显示的错误。

/var/log/ldapscripts.log 确实显示了关于“无效凭证”的投诉。但是，无论我将实际的 cn=admin 密码放入 /etc/ldapscripts/ldapscripts.passwd 中，还是在其中放入单词“secret”，都会发生这种情况。
/var/log/ldapscripts.log
root@my-host:/var/log# cat ldapscripts.log

请注意，上面的日志输出中出现了我的用户名 (my-username)。尽管我在之后运行了所有 OpenLDAP 命令，但结果仍然如此。苏 -l 根。
我缺少哪个步骤才能成功使用 ldapscripts？
答案1
遇到了类似的问题，即同样的错误：ldap_bind：无效凭证（49）
解决这个问题的唯一方法是删除 ldapscripts.passwd 并使用
# echo -n "mypassword" > /etc/ldapscripts/ldapscripts.passwd
（之前我直接用 vi 输入密码编辑文件）。HTH。
