安装失败
Debian 9，通过apt安装ApacheDS，出错如下：
root@debian:~# apt-get install apacheds
...
Failed to start apacheds.service: Unit apacheds.service is not loaded properly: Invalid argument.
See system logs and 'systemctl status apacheds.service' for details.
invoke-rc.d: initscript apacheds, action "start" failed.

无法删除
进行删除，但失败，如下：

解决方法
根据提示判断是ExecStart有问题，于是屏蔽问题ExecStart，重新删除：
root@debian:~# vim /lib/systemd/system/apacheds.service

后记
也许是Debian9的ApacheDS安装包存在bug，没有深入研究，选择slapd代替。
