Summary

This update changes the default behavior to require X.509 validation

Previous behavior can reverted by setting `ldapVerify => "none"` when

NOTE: this update is a prerequisite for LemonLDAP::NG's CVE-2020-16093

For Debian 10 buster, this problem has been fixed in version
0.4-1+deb10u1.

We recommend that you upgrade your libapache-session-ldap-perl packages.
