Java 升级 8 到 11 导致 LDAPS 连接出现问题(连接或出站已关闭)

Question

java升级后出现的这个问题:

具有 DNS 别名的 LDAP 无法与 java 11.0.2 连接
使用 java 8

下面的 DNS 别名保持不变，这里没有变化，唯一的变化是 java 升级 8 到 11:

$ nslookup ad1.XXXXX.zz

Server:         10.222.249.209
Address:        10.222.249.209#53

Name:   ad1.XXXXX.zz
Address: 10.222.249.205
Name:   ad1.XXXXX.zz
Address: 10.222.249.204
Name:   ad1.XXXXX.zz
Address: 10.222.249.210

LDAP 直接 IP 与 java 11.0.2 没有问题:

$ nslookup qdegsf.XXXXX.zz

Server:         10.222.249.209
Address:        10.222.249.209#53

Name:   qdegsf.XXXXX.zz
Address: 10.222.249.210

工艺参数:

/opt/3rdparty/jdk_installed/jdk-11.0.2/bin/java -Dsserver -Djdk.serialFilter=* -Dfile.encoding=UTF8 -Djavax.net.ssl.trustStore=/opt/3rdparty/tomcat/conf/svrtrust - Djavax.net.ssl.trustStorePassword=XXXX -Djavax.net.ssl.keyStore=/opt/3rdparty/tomcat/conf/svrkeystore.jks

以下是建立 ldap 连接时的问题跟踪

Answer 1

根据您使用的 Java 8 版本，此错误可能有多种原因:

Java 11(和 Java 8 的最新版本)现在强制执行主机名
建立 SSL 连接时的验证。所以服务器的
证书与您尝试连接的主机名非常匹配。

Java 11 还具有更新的密码套件和 TLS 版本，并弃用了一些旧密码套件。您可能想要启用 SSL
调试以查看 SSL 层上交换的内容。

最后，TLS(1.3) 存在几个问题，Java 11 早期版本中的密码套件，因此您可能需要切换到
最新更新 (11.0.5)
