这个问题困扰了我好久了。我花了好几个小时试图找出问题所在，但就是解决不了。当我尝试使用sudo apt-get install slapd安装的所有其他 OpenLDAP 和 ldap-utils 时，发生了以下情况：
The following NEW packages will be installed:

“53358740 str2entry：attributeType objectClass #0 的值无效（语法 1.3.6.1.4.1.1466.115.121.1.38）”
似乎对于找到解决问题的方法至关重要。
我认为您的 objectClass 定义格式不正确。安装 ldap 时，它会将一些默认 objectClass 定义添加到您的 ldap 树中。其中一个可能已损坏或被修改，因此尝试添加时会失败。
修复 objectClass
grep -R str2entry /etc/
应该可以帮助你找到文件
或者也许最简单的解决方案是完全清除您的 ldap 安装，以便您从头开始安装过程。
