I have been fooling arround with Net::LDAP to query an exchange system. I want to get the NT account name
from the query, but I get a value that looks like this:

010500000000000515000000C60B7E00B719917EF21E5310FA0E0000

after reading some stuff over at M$oft, it seems that Exchange stores the NT SID in hex format
as opposed to binary (as the OS does). I found this code snippet for VB to convert it to binary:
'The SID is stored in a hexadecimal representation of the binary SID
  'so we convert it and store it in a byte array
  tmp = Len(strSID) / 2 - 1
  ReDim bByte(tmp) As Byte
  For i = 0 To tmp - 1
    bByte(i) = CInt("&h" & Mid(strSID, (i * 2) + 1, 2))
  Next
  
  'Allocate space for the strings so the API won't GPF
  strName = Space(64)
  strDomain = Space(64)
  
  'Get the NT Domain and UserName
  'Note: This can't be done from VBScript directly
  'because VBScript doesn't support making the
  'LookupAccountSid API call
  ret = LookupAccountSid(vbNullString, bByte(0), strName, Len(strName)
+, strDomain, Len(strDomain), iType

can anyone help me with the first part here where the hex value is stored in a byteArray ?
i assume we need pack here but, sadly, i am one of the many who do not understand pack.

humbly,
