## Description

In Pivotal Spring-LDAP versions 1.3.0 - 2.3.1, when connected to some LDAP
servers, when no additional attributes are bound, and when using LDAP
BindAuthenticator with
org.springframework.ldap.core.support.DefaultTlsDirContextAuthenticationStrategy
as the authentication strategy, and setting userSearch, authentication is
allowed with an arbitrary password when the username is correct. This
occurs because some LDAP vendors require an explicit operation for the LDAP
bind to take effect.
