SSL handshake failed: LDAP链接失败解决方法

部署后系统抛出异常：

org.apache.directory.ldap.client.api.exception.InvalidConnectionException: SSL handshake failed.

 怀疑证书无效或者过期，去到应用端服务器，检查证书有效期，果然是证书过期。

$ openssl x509 -noout -dates -in ca.txt
notBefore=Mar 10 12:00:00 2018 GMT
notAfter=Mar 10 12:00:00 2023 GMT

解决方案：

重新生成证书后部署
