Below is a simple concept code in PowerShell that makes it:

Add-Type -Language "CSharp" -TypeDefinition @"
using System;
using System.Text;
using System.Runtime.InteropServices;

namespace PInvoke
{
	public class ntdsapi
	{
		[DllImport("ntdsapi.dll", SetLastError = true, CharSet = CharSet.Auto)]
		public static extern UInt32 DsMakePasswordCredentials(
			[MarshalAs(UnmanagedType.LPWStr)] String User,
			[MarshalAs(UnmanagedType.LPWStr)] String Domain,
			[MarshalAs(UnmanagedType.LPWStr)] String Password,
			out IntPtr pAuthIdentity
		);

		[DllImport("ntdsapi.dll", SetLastError = true, CharSet = CharSet.Auto)]
		public static extern void DsFreePasswordCredentials(
			IntPtr AuthIdentity
		);

		[DllImport("ntdsapi.dll", SetLastError = true, CharSet = CharSet.Auto)]
		public static extern UInt32 DsBindWithCred(
			[MarshalAs(UnmanagedType.LPWStr)] String DomainControllerName,
			[MarshalAs(UnmanagedType.LPWStr)] String DnsDomainName,
			IntPtr AuthIdentity,
			out IntPtr phDS
		);

		[DllImport("ntdsapi.dll", SetLastError = true, CharSet = CharSet.Auto)]
		public static extern UInt32 DsUnBind(
			IntPtr phDS
		);

		[DllImport("ntdsapi.dll", SetLastError = true, CharSet = CharSet.Auto)]
		public static extern UInt32 DsAddSidHistory(
			IntPtr hDS,
			UInt32 Flags,
			[MarshalAs(UnmanagedType.LPWStr)] String SrcDomain,
			[MarshalAs(UnmanagedType.LPWStr)] String SrcPrincipal,
			[MarshalAs(UnmanagedType.LPWStr)] String SrcDomainController,
			IntPtr SrcDomainCreds,
			[MarshalAs(UnmanagedType.LPWStr)] String DstDomain,
			[MarshalAs(UnmanagedType.LPWStr)] String DstPrincipal

	}

Thanks. DSInternals actually uses direct MS-DRSR RPC calls instead of utilizing ntdsapi.dll. The code would thus need to be implemented in C++ in the DRSConnection class and by calling IDL_DRSAddSidHistory.

Initial point of this issue was to write values into "sIDHistory" attribute of target objects without taking AD database offline, like "Add-ADDBSidHistory" requires.
Replication protocol allows to read everything, including password hashes, but it doesn't allow to perform writes. Am I wrong about it?
