我写了一个小程序来对ldap进行身份验证。

import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;

class SAuth {
    public static void main(String[] args) {

    Hashtable env = new Hashtable(11);
    env.put(Context.INITIAL_CONTEXT_FACTORY, 
        "com.sun.jndi.ldap.LdapCtxFactory");
    env.put(Context.PROVIDER_URL, "ldap://xx.xx.xx.xx:yyyy/");

    // Authenticate as S. User and password "mysecret"
    env.put(Context.SECURITY_AUTHENTICATION, "username");
    env.put(Context.SECURITY_PRINCIPAL, "cn=orcladmin");
    env.put(Context.SECURITY_CREDENTIALS, "password");

    try {

        DirContext ctx = new InitialDirContext(env);
            System.out.println(" i guess the connection is sucessfull :)");

        // Do something useful with ctx 

        // Close the context when we're done
        ctx.close();
    } catch (NamingException e) {
        e.printStackTrace();
    }

} }

我收到以下错误:

javax.naming.AuthenticationNotSupportedException: orcladmin
        at com.sun.jndi.ldap.sasl.LdapSasl.saslBind(LdapSasl.java:100)
        at com.sun.jndi.ldap.LdapClient.authenticate(LdapClient.java:214)

但是,如果我尝试使用ldap cmd行和相同的用户凭据访问ldap目录,它可以顺利运行。 例如:

ldapsearch -p <port> -h <ip> -D "cn=orcladmin" -w "password"  objectClass=*

返回有关数据。 我想java程序有问题,但dunno wat。

答案 0 :(得分:3)

尝试更改

env.put(Context.SECURITY_AUTHENTICATION, "username");

env.put(Context.SECURITY_AUTHENTICATION, "simple");
