我在从应用程序连接到 LDAPS 时遇到问题。我已在 JRE 密钥库上导入了所有必需的证书。
当我将以下字符串放入 java.security 中时，我可以调用 LDAP
jdk.tls.disabledAlgorithms=MD5, SSLv3, DSA, RSA keySize < 2048
当我将此行更改为
jdk.tls.disabledAlgorithms=MD5, DSA, DESede, DES_CBC, DHE, RC4, SSLv3, ECDH_anon, DH_anon, NULL, DH keySize < 768, RSA keySize < 2048
我的连接失败并出现以下错误：
