A trust relationship exists between two Microsoft Windows Server 2003 forests in your organization. When you try to use the dsmod command to add a user from one forest to a group in the other forest, you receive an error message that is similar to the following:
dsmod failed: The specified user does not exist
type dsmod /? for help.
For example, suppose that a trust relationship exists between two forests that are named forestA.local and forestB.local. You use the following command line to add User1 from forestA.local to the Administrators group in forestB.local:
dsmod group "cn=administrators,cn=Builtin,dc=forestB,dc=local" -addmbr "cn=user1,cn=users,dc=forestA,dc=local"
In this scenario, you receive the following error message:
dsmod failed:cn=administrators,cn=Builtin,dc=forestB,dc=local:The specified user does not exist.
type dsmod /? for help.
This behavior occurs because the dsmod command is not designed to support scenarios where a trust relationship exists between forests.
To work around this behavior, use one of the following methods:
  • Use Active Directory Users and Computers to add the user to the group.
  • Use the following Microsoft Visual Basic script to add the user to the group. Name the script Dsaddmbr.vbs.
    for each strArg in wscript.Arguments.Named	strValue = wscript.Arguments.Named.Item(strArg)	select case lcase(strArg)		case "g" ' logging			groupDN = strValue		case "u"			userDN = strValue		case "?","help","h"			wscript.echo "cscript /nologo " & wscript.scriptname & " [/g:groupDN] [/u:userDN]"			wscript.quit				end selectnextset oProv = GetObject("LDAP:")set oGroup = oProv.OpenDSObject("LDAP://" & groupDN, vbnullstring, vbnullstring, 1)set oUser = oProv.OpenDSobject("LDAP://" & userDN, vbnullstring, vbnullstring, 1)oValue = oUser.Get("objectSid")oString = OctetString2String(oValue)oGroup.PutEx 3, "member", Array("<Sid=" & oString & ">")oGroup.SetInfoFunction OctetString2String(byVal OctetStr)dim resultdim j, loByte, hiByte    result = ""    for j = lbound(OctetStr) to ubound(OctetStr)        hiByte = ascb(midb(OctetStr,j+1,1))        loByte = hiByte mod 16        hiByte = hiByte \ 16        result = result & hex(hiByte) & hex(loByte)    next    OctetString2String = resultEnd Function
    To run the script, use the following syntax:
    cscript /nologo dsaddmbr.vbs [/g:groupDN] [/u:userDN]
