Question

我正在开发一个应用程序spring-boot，用于使用LdapTemplate获取Ldap存储库的用户信息。

我使用用户电子邮件作为uid，当用户更新他的电子邮件时我也必须更新他的uid。问题是下面的方法适用于所有Person字段，但不适用于UID。我收到一个错误：

reduce

这是一个片段：

    let shortDescriptor = NSSortDescriptor(key: key, ascending: ascending)


    fetchedResultViewController.fetchRequest.sortDescriptors = [shortDescriptor]

    NSFetchedResultsController<NSFetchRequestResult>.deleteCache(withName: fetchedResultViewController.cacheName)

    do {
        try fetchedResultViewController?.performFetch()
    } catch let error as NSError {
        print("Error in fetch \(error)")
    }

BuildDn：

LDAP: error code 64 - value of naming attribute 'uid' is not present in entry

映射

public void updateUser(Person p) throws InvalidNameException {
    Name dn = buildDn(p);
    DirContextOperations context = ldapTemplate.lookupContext(dn);
    LdapMapper.mapToContext(p, context);
    ldapTemplate.modifyAttributes(context);
}

你有什么想法来修复这个错误吗？

祝你好运

Answer 1

您无法对uid字段执行修改，而是必须重命名记录以更新uid。

像这样：

ldapTemplate.rename("uid=oldUid,ou=People,dc=example,dc=com", "uid=newUid,ou=People,dc=example,dc=com")

而不是

ldapTemplate.modifyAttributes(context);。

Answer 2

Define the configuratons  for LdapContextSource and LdapTemplate

Name dn = LdapNameBuilder.newInstance().add("uid", uid).build();

Name dnNew = LdapNameBuilder.newInstance().add("uid", newUid).build();

ldapTemplate.rename(dn, dnNew);

这将更新uid。

https://docs.spring.io/spring-ldap/docs/current/apidocs/org/springframework/ldap/core/LdapTemplate.html

void    rename(Name oldDn, Name newDn)

将LDAP树中的条目移动到新位置。

ldapTemplate的重命名方法以某种方式起作用，但是我将如何重命名属性本身？：

  @Test(expected = SchemaViolationException.class)
  public void testModifyRdnUsingDirContext() {
      LdapName name = LdapNameBuilder.newInstance()
        .add("ou", "people")
        .add("uid", "test")
        .build();
      LdapName newName = LdapNameBuilder.newInstance()
        .add("ou", "people")
        .add("uid", "test1")
        .build();
      // seems disfuctional, because it is not possible to change the value
      // of the uid attribute to the new one beforehand or afterwards. This
      // problem might be unboundID (embedded ldap server) specific.
      ldapTemplate.rename(name, newName);
      DirContextOperations context = ldapTemplate.lookupContext(newName);
      context.setAttributeValue("uid", "test1");
      ldapTemplate.modifyAttributes(context);
    }

修改ldap存储库中的uid
