有人可以告诉我如何在Apache LDAP API中正确使用LdapNetworkConnection的移动方法，或者这是他们的API中的一个错误？



我正在使用Apache LDAP API来帮助我们的客户连接到他们的LDAP服务器，并通过我们的程序做他们想做的事情。但是当我在LdapNetworkConnection中使用mothod public void move( String entryDn, String newSuperiorDn ) throws LdapException时我无法做到。 这是我的用户.ldif：

version: 1
dn: dc=myorg,dc=com
objectClass: domain
objectClass: top
dc: myorg
dn: ou=Users,dc=myorg,dc=com
objectClass: organizationalUnit
objectClass: top
ou: Users
dn: ou=Groups,dc=myorg,dc=com
objectClass: organizationalUnit
objectClass: top
ou: Groups
dn: cn=LdapTester1,ou=Users,dc=myorg,dc=com
objectClass: inetOrgPerson
objectClass: organizationalPerson
objectClass: person
objectClass: top
cn: Test1 Ldap
sn: Ldap
uid: ldaptest1
userPassword: 12345
dn: cn=elecharny,ou=system
objectClass: top
objectClass: person
objectClass: extensibleObject
sn:: RW1tYW51ZWwgTMOpY2hhcm55
cn: elecharny
givenName: Ele
userPassword:: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKbHnLFs5N2PHk0gkyI/g3XeIdjxnWOAW5RVap4zWZuNY4gNGH1MhfHPVHcy6WEMoo+zaxU0Xh+Iv6BzrIa70IUCAwEAAQ== })

我想将条目cn=elecharny,ou=system移动并期望它是cn=elecharny,ou=Users,dc=myorg,dc=com. 运行代码时，移动操作之前的所有断言都可以。这意味着条目ou=Users,dc=myorg,dc=com存在。但我得到了以下例外：

org.apache.directory.api.ldap.model.exception.LdapOperationErrorException: OPERATIONS_ERROR: failed for MessageType : MODIFYDN_REQUEST
Message ID : 4
    ModifyDN Response
        Entry : 'cn=elecharny,ou=system'
        Delete old Rdn : false
        New superior : 'ou=Users,dc=myorg,dc=com'

org.apache.directory.api.ldap.model.exception.LdapOperationErrorException: ERR_256_NO_SUCH_OBJECT Entry ou=Users,dc=myorg,dc=com does not exist!

太令人困惑了。我已经尝试了几天。不幸的是，我还没有找到解决方案。 有人可以帮助我吗？

    // Define the DirectoryService
@CreateDS(name = "myDS",
        partitions = {
                @CreatePartition(name = "test", suffix = "dc=myorg,dc=com")
        })
// Define the LDAP protocol layer
@CreateLdapServer(
        transports = {
                @CreateTransport(protocol = "LDAP"),
                @CreateTransport(protocol = "LDAPS")
        },
        allowAnonymousAccess = true,
        extendedOpHandlers = {StartTlsHandler.class}
)
// Inject a file containing entries
@ApplyLdifFiles({"users.ldif"})
public class LdapConnectTest{
    @Test
    public void testMove() throws Exception {
        LdapConnectionConfig connectionConfig = new LdapConnectionConfig();
        connectionConfig.setLdapHost(Network.LOOPBACK_HOSTNAME);
        connectionConfig.setLdapPort(ldapServer.getPort());
        connectionConfig.setName("cn=LdapTester1,ou=Users,dc=myorg,dc=com");
        connectionConfig.setCredentials("12345");
        try(LdapNetworkConnection ldapNetworkConnection = new LdapNetworkConnection(connectionConfig)) {
            ldapNetworkConnection.connect();
            ldapNetworkConnection.bind();
            assertTrue(ldapNetworkConnection.isConnected());
            assertTrue(ldapNetworkConnection.isAuthenticated());
            assertTrue(ldapNetworkConnection.exists("cn=elecharny,ou=system"));
            assertTrue(ldapNetworkConnection.exists("ou=Users,dc=myorg,dc=com"));
            ldapNetworkConnection.move("cn=elecharny,ou=system", "ou=Users,dc=myorg,dc=com");
            assertTrue(ldapNetworkConnection.exists("cn=elecharny,ou=Users,dc=myorg,dc=com"));
            ldapNetworkConnection.unBind();
            assertFalse(ldapNetworkConnection.isConnected());
            assertFalse(ldapNetworkConnection.isAuthenticated());
        }
    }
}

如果某处存在错误，则在错误日志记录中：ERR_256_NO_SUCH_OBJECT错误可能是指不存在的条目dn: cn=elecharny,ou=system - 它不能，它的 DN 无效 - 而不是ou=Users,dc=myorg,dc=com。

您需要

创建system组织单位(如果尚未创建((LDIF 中不存在(，并添加您认为要移动的条目：

dn: ou=system,dc=myorg,dc=com
objectClass: organizationalUnit
objectClass: top
ou: system
dn: cn=elecharny,ou=system,dc=myorg,dc=com
objectClass: top
objectClass: person
objectClass: extensibleObject
sn:: RW1tYW51ZWwgTMOpY2hhcm55
cn: elecharny
givenName: Ele
userPassword:: MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBAKbHnLFs5N2PHk0gkyI/g3XeIdjxnWOAW5RVap4zWZuNY4gNGH1MhfHPVHcy6WEMoo+zaxU0Xh+Iv6BzrIa70IUCAwEAAQ== })

创建一个包含缺失条目的新 ldif 文件并使用 ldapadd -f new_ldif 。
