Question

为了在Active Directory服务中搜索特定用户，我们使用了ldap_search_sW API。但是，在Windows Server 2012的情况下崩溃我的exe。没有返回错误代码，EXE就停止工作了。

我的EXE是32位应用程序。所以我想它会从“SysWow64”目录加载。以下是关于如何完成调用的示例行： -

pld声明：

type // record declaration begins
  {$EXTERNALSYM PLDAP}
  PLDAP = ^LDAP;
  {$EXTERNALSYM LDAP}
  LDAP = record

      ld_sb: record
        sb_sd: ULONG;
        Reserved1: array [0..(10 * sizeof(ULONG))] of Byte;
       sb_naddr: ULONG;   // notzero implies CLDAP available
       Reserved2: array [0..(6 * sizeof(ULONG)) - 1] of Byte;
       //
       //  Following parameters MAY match up to reference implementation of LDAP
      //

    ld_host: PChar;
    ld_version: ULONG;
    ld_lberoptions: Byte;

    //
   //  Safe to assume that these parameters are in same location as
   //  reference implementation of LDAP API.
   //

    ld_deref: ULONG;

    ld_timelimit: ULONG;
    ld_sizelimit: ULONG;

    ld_errno: ULONG;
    ld_matched: PChar;
    ld_error: PChar;
    ld_msgid: ULONG;

    Reserved3: array  [0..(6*sizeof(ULONG))] of Byte;

    //
    //  Following parameters may match up to reference implementation of LDAP API.
    //

    ld_cldaptries: ULONG;
    ld_cldaptimeout: ULONG;
    ld_refhoplimit: ULONG;
    ld_options: ULONG;

end; // record declaration end

 pld : PLDAP;
 pld := Session.pld; // session PLD is assigned as is to it
 The sessions' PLD is initialized as 
 ldappld := ldap_initW(PWideChar(ldapServerW), ldapPort)  // this is eventually assigned to Session's PLD which is assigned to the PLD used Below

 LdapCheck(ldap_search_sW(pld, PWideChar('DC=esbs,DC=local'), LDAP_SCOPE_SUBTREE, '(objectCategory=user)', nil, 0, plmSearch));

我应该采取什么步骤？

以下是EXE崩溃的Windows转储：

我们已经解决了这个问题，我在这里发布解决方案。我们使用的ldap_search_sW函数没有问题。在连接到ADS之前，我们用于验证提供的用户名和密码。然后我们使用ldap_initW，ldap_set_optionW和ldap_simple_bind_sW连接到服务器。

然后ldap_search_sW读取用户列表以读取用户列表。在Server 2012中，如果跳过了身份验证部分，则exe不会崩溃。身份验证完成如下： -

function AuthenticateADSUserW(ADSUserName, ADSPassword, ADSip: String;Var Fun_Obj:String): Boolean;
var
   AuthResult : Integer;
   hInstance:    THandle;
   ADSServerName,
   ADSUsrNam,
   ADSPwd,
   ADSPortNo,
   Error: Array [0..255] of char;
   ldapDomain,
   ldapUserName,
   ldapPassword    : WideString;
   hr            : integer;
   obj           : IADs;
 begin
   try
     Result  := False;
         Fun_Obj := '';
// Insert code to securely retrieve the user name and password.
try
    ldapDomain    := UTF8Decode(ADSip);
    ldapUserName  := UTF8Decode(ADSUserName);
    ldapPassword  := UTF8Decode(ADSPassword);

    CoInitialize(Nil); //Added By Sameer

    hr := ADsOpenObject('LDAP://'+ldapDomain,
                       ldapUserName,
                       ldapPassword,
                       ADS_SECURE_AUTHENTICATION,
                       IADs,
                       obj);
    Fun_Obj := obj.ADsPath ;
    if  Succeeded(hr) then
      Result := True;

except
  on e : exception do
  begin
    escan.Updatelog('Error '+e.ClassName + ': ' + e.Message,1,0);
      Result := False;
  end;
  //lblMessage.Caption  := e.ClassName + ': ' + #13#10 + e.Message;
end;
finally
   CoUninitialize;
 end;
end;

我们跳过了这个，而是通过检索提供的用户名的基本DN进行了身份验证。如果返回BASE DN，则认为用户已通过身份验证。如果返回空，则不对用户进行身份验证。

希望它有所帮助。

ldap_search_sW函数在Windows Server 2012 R2 X64上崩溃了吗？
