Upgrade to JDK 1.8.0_181 version may throw "javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No subject alternative DNS name matching" when configuring an MFT Authenticator to use LDAP over SSL and the DNS name does not match the Certificate DN.

Oracle JDK 1.8.0_181 added endpoint validation to make sure that the LDAP DNS name matches the Certificate CN or the Certificate Subject Alternative DNS Name.

Improve LDAP support
Endpoint identification has been enabled on LDAPS connections.

To improve the robustness of LDAPS (secure LDAP over TLS ) connections, endpoint identification algorithms have been enabled by default.

Note that there may be situations where some applications that were previously able to successfully connect to an LDAPS server may no longer be able to do so. Such applications may, if they deem appropriate, disable endpoint identification using a new system property: com.sun.jndi.ldap.object.disableEndpointIdentification.

Define this system property (or set it to true) to disable endpoint identification algorithms.
