I'm trying to setup an ldap server on ubuntu 16.04. During installation of ldap-utils and slapd I get the following:

Setting up slapd (2.4.42+dfsg-2ubuntu3.2) ...
  Moving old database directory to /var/backups:

  Creating initial configuration... done.

The logs from running journalctl -xe look like this:

After running sudo apt-get remove --purge slapd and reinstalling it. I still get the same error upon installation. How do I fix this issue?

The issue was that something was already using the address, as you can see from the log files here:

I realized that earlier I had installed samba and smbldap-tools. Removing both of those with sudo apt-get remove --purge samba smbldap-tools results in the following:
