Question

我正在尝试查询LDAP服务器以查找LDAP用户并将其导入我的系统。但是，当我尝试执行此操作时，请求会引发DirectoryOperationException，说The object does not exist。

ldapConnection.AuthType = AuthType.Negotiate;

if (ldapDomain.UseEncryption)
{
    ldapConnection.SessionOptions.SecureSocketLayer = true;
    ldapConnection.SessionOptions.StartTransportLayerSecurity(null);
}

var credentials = new NetworkCredential(loginName, password, ldapDomain.Name);
ldapConnection.Bind(credentials);

var filter = String.Format("(&(objectCategory=person)(objectClass=user)(anr={0})(!(UserAccountControl:1.2.840.113556.1.4.803:=2)))", loginName);
var request = new SearchRequest(containerDistinguishedName, filter, SearchScope.Subtree);
var response = ldapConnection.SendRequest(request) as SearchResponse;
var entry = response.Entries[0];

我只需要对抗Microsoft / Windows LDAP服务器。目前，containerDistinguishedName为空，但可以填入值以进一步限制搜索过滤器。

从外观来看，空containerDistinguishedName指的是根DSE，但subtree范围的搜索应该仍然有效，假设连接的授权状态允许拖网DIT（Root DSE）仅在搜索结果为base时才会在搜索结果中返回。尝试使用“{1}}的”最高“DIT的基础对象，类似containerDistinguishedName。

LdapConnection SearchRequest抛出对象不存在错误
