結論から。
sudo apt -y install ldap-utils
無事インストールできました。
$ ldapsearch -V
ldapsearch: @(#) $OpenLDAP: ldapsearch (Ubuntu) (May 30 2017 19:20:53) $
buildd@lgw01-18:/build/openldap-JXEADB/openldap-2.4.42+dfsg/debian/build/clients/tools
(LDAP library: OpenLDAP 20442)
CentOS だったらこんな感じですね。
sudo yum -y install openldap-clients
$ ldapsearch -V
ldapsearch: @(#) $OpenLDAP: ldapsearch 2.4.44 (Aug 4 2017 14:23:23) $
mockbuild@c1bm.rdu2.centos.org:/builddir/build/BUILD/openldap-2.4.44/openldap-2.4.44/clients/tools
(LDAP library: OpenLDAP 20444)
普段 CentOS ユーザなので、ちょっと迷いました。
