I installed the package available in xenial-proposed as you can see below: root@openldap-xenial-sru:~# apt policy slapd slapd: Installed: 2.4.42+dfsg-2ubuntu3.7 Candidate: 2.4.42+dfsg-2ubuntu3.7 Version table: *** 2.4.42+dfsg-2ubuntu3.7 500 500 http://archive.ubuntu.com/ubuntu xenial-proposed/main amd64 Packages 100 /var/lib/dpkg/status 2.4.42+dfsg-2ubuntu3.6 500 500 http://archive.ubuntu.com/ubuntu xenial-updates/main amd64 Packages 500 http://security.ubuntu.com/ubuntu xenial-security/main amd64 Packages 2.4.42+dfsg-2ubuntu3 500 500 http://archive.ubuntu.com/ubuntu xenial/main amd64 Packages
And after executing the steps presented in the Test case section, the slapd process did not die: root@openldap-xenial-sru:~# ps aux | grep slapd openldap 2078 0.0 4.5 2094540 730664 ?
