Question

我在两个域中有两个Active Directory：domain1.xx和domain2.xx 我有一个属于domain1.xx的用户名为user1。我可以使用user1在domain1上进行LDAP查询。 user1在domain2.xx上有一个读取权限，我已经使用AD Explorer对其进行了测试，并且它有效。问题是当我使用java时，它会返回我的异常：错误：[LDAP：错误代码49 - 80090308：LdapErr：DSID-0C090334，注释：AcceptSecurityContext错误，数据525，vece

这是在domain1中连接查询的代码，它起作用：

package ad;

import java.util.Enumeration;
import java.util.Hashtable;
import javax.naming.AuthenticationException;
import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.Attribute;
import javax.naming.directory.DirContext;
import javax.naming.directory.SearchControls;
import javax.naming.directory.SearchResult;

public class AD {


    static DirContext ldapAuthenticate(String password, String userdn) throws Exception {
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        //set security credentials, note using simple cleartext authentication
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, userdn);
        env.put(Context.SECURITY_CREDENTIALS, password);
        //connect to my domain controller
        env.put(Context.PROVIDER_URL, "ldap://domain1.xx");
        //Create the initial directory context
        DirContext ctx = null;
        try {

            ctx =  new javax.naming.directory.InitialDirContext(env);

        } catch (AuthenticationException e) {

            System.out.println("ERROR: "+e.getMessage());
        } catch (Exception e) {
            System.out.println("ERROR: "+e.getMessage());
                       //something went wrong
            ///handle in some way
        }
        return ctx;
    }

    public static void main(String[] args) throws Exception {
        DirContext context = ldapAuthenticate("xxxxxx","user01@domain1.xx");
        String userdn = "dc=domain1,dc=xx";
        SearchControls searchCtrls = new SearchControls();
        searchCtrls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        String[] attributes = {"member"};
        searchCtrls.setReturningAttributes(attributes);

        //Change the NameOfGroup for the group name you would like to retrieve the members of.
        String filter ="objectclass=*";
        NamingEnumeration values = context.search(userdn, filter, null);

        //Loop through the search results
        while (values.hasMoreElements()) {
            SearchResult sr = (SearchResult) values.next();
            System.out.println(">>>" + sr.getName());
            javax.naming.directory.Attributes attrs = sr.getAttributes();

            if (null != attrs) {
                for (NamingEnumeration ae = attrs.getAll(); ae.hasMoreElements();) {
                    Attribute atr = (Attribute) ae.next();
                    String attributeID = atr.getID();
                    Enumeration vals = atr.getAll();

                    if (vals.hasMoreElements()) {
                        String username = (String) vals.nextElement();
                        System.out.println("Username: " + username);

                    }
                }
            } else {
                System.out.println("No members for groups found");
            }
        }
    }
}

当我想查询domain2.xx时，我有例外：

package ad;

import java.util.Enumeration;
import java.util.Hashtable;
import javax.naming.AuthenticationException;
import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.Attribute;

import javax.naming.directory.SearchControls;
import javax.naming.directory.SearchResult;

public class AD {


    static DirContext ldapAuthenticate(String password, String userdn) throws Exception {
        Hashtable env = new Hashtable();
        env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
        //set security credentials, note using simple cleartext authentication
        env.put(Context.SECURITY_AUTHENTICATION, "simple");
        env.put(Context.SECURITY_PRINCIPAL, userdn);
        env.put(Context.SECURITY_CREDENTIALS, password);
        //connect to my domain controller
        env.put(Context.PROVIDER_URL, "ldap://domain2.xx");
        //Create the initial directory context
        DirContext ctx = null;
        try {

            ctx =  new javax.naming.directory.InitialDirContext(env);

        } catch (AuthenticationException e) {

            System.out.println("ERROR: "+e.getMessage());
        } catch (Exception e) {
            System.out.println("ERROR: "+e.getMessage());
                       //something went wrong
            ///handle in some way
        }
        return ctx;
    }

    public static void main(String[] args) throws Exception {
        DirContext context = ldapAuthenticate("xxxxxx","user01@domain1.xx");
        String userdn = "dc=domain2,dc=xx";
        SearchControls searchCtrls = new SearchControls();
        searchCtrls.setSearchScope(SearchControls.SUBTREE_SCOPE);
        String[] attributes = {"member"};
        searchCtrls.setReturningAttributes(attributes);

        //Change the NameOfGroup for the group name you would like to retrieve the members of.
        String filter ="objectclass=*";
        NamingEnumeration values = context.search(userdn, filter, null);

        //Loop through the search results
        while (values.hasMoreElements()) {
            SearchResult sr = (SearchResult) values.next();
            System.out.println(">>>" + sr.getName());
            javax.naming.directory.Attributes attrs = sr.getAttributes();

            if (null != attrs) {
                for (NamingEnumeration ae = attrs.getAll(); ae.hasMoreElements();) {
                    Attribute atr = (Attribute) ae.next();
                    String attributeID = atr.getID();
                    Enumeration vals = atr.getAll();

                    if (vals.hasMoreElements()) {
                        String username = (String) vals.nextElement();
                        System.out.println("Username: " + username);

                    }
                }
            } else {
                System.out.println("No members for groups found");
            }
        }
    }
}

任何人都可以帮助解决这个问题。 user01@domain1.xx可以读取domain2.xx中的所有OU，我已尝试使用AD资源管理器。

您发布的

身份验证错误包含可能有用的特殊代码。在您的情况下，代码是525（ AcceptSecurityContext错误，数据525 ）。代码525表示＆＃34;用户未找到＆＃34;。根据您的代码判断，您正在重复使用同一个用户 - user1 @ domain1 。此用户仅在域1中存在。域2不知道此用户，因此AD域控制器拒绝身份验证尝试。

附加到问题的代码示例针对特定域控制器而非全局编录。尝试执行以下操作：

使用InitialLdapContext而不是InitialDirContext
绑定到全局目录而不是域控制器。为此，请使用URL ldap：// FQDN：3268 。请不要该端口是3268。

请注意，端口3268不安全。

希望这有帮助。
