通过 TLS 连接到 LDAP 服务器失败，但出现异常
org.springframework.ldap.UncategorizedLdapException: Failed to negotiate TLS session; nested exception is javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

我已经检查了我的密钥库中是否存在适当的证书，并且导入了缺失的证书，如PKIX path building failed while making SSL connection中所述，但是我仍然遇到异常。有任何想法吗？
谢谢，
