An issue was discovered in LemonLDAP::NG (aka lemonldap-ng) 2.0.13. When
using the RESTServer plug-in to operate a REST password validation service
(for another LemonLDAP::NG instance, for example) and using the Kerberos
authentication method combined with another method with the Combination
authentication plug-in, any password will be recognized as valid for an
existing user.
