javax.naming.ServiceUnavailableException:套接字关闭

Question

我试图通过LDAP授权用户。

public Authentication authenticate(Authentication auth) throws AuthenticationException {
        String username = getUserNameFromAuth(auth);
        String password = auth.getCredentials().toString();
        HelpDescUser userDetails = (HelpDescUser) userDetailsService.loadUserByUsername(username);
        String email = userDetails.getEmail();
        String url = "ldap://" + ldapHost + ":" + port + "/";
        ActiveDirectoryLdapAuthenticationProvider ldapProvider =
                    new ActiveDirectoryLdapAuthenticationProvider(null, url, rootDn);
        ldapProvider.setSearchFilter(filter);
        Authentication authenticate = ldapProvider.authenticate(new UsernamePasswordAuthenticationToken(email, password));
        if (authenticate.isAuthenticated()) {
            return new UsernamePasswordAuthenticationToken(userDetails, password, userDetails.getAuthorities());
        }
}

我收到这封信：

怎么搞错了？是我这边的问题，还是LDAP方面的问题？

Answer 1

别担心，我只是试着连接ldap://和端口636。正确的方法是发出ldaps://请求或设置端口389。

Answer 2

检查服务器details.Are，您可以切换到服务器。

Answer 3

检查LDAP是否已启动。看起来LDAP已经关闭了。
