    Converting binary sid's to a hex string

    I am trying to create a hexstring of a NT4 user account sid which I can in
    turn use to query an exchange 55 database. I believe I need to convert a
    binary sid to a hex string. ADsSID com object will do this for me however it
    is a little slow. Can anybody point me in the right direction to converting
    a PySID to a hexstring.
    Thx

    import win32netcon
    import win32net
    import win32security
    def report():
    resume = 0
    while 1:
    filter = win32netcon.FIL TER_NORMAL_ACCO UNT
    data, total, resume = win32net.NetUse rEnum('nt4pridc 1', 20, filter,
    resume)
    for user in data:
    MySid, string, int = win32security.L ookupAccountNam e('nt4pridc1',
    user['name'])
    sString = win32security.C onvertSidToStri ngSid(MySid)
    print MySid
    print sString
    if resume ==0:
    break

    report()
    ## sString prints = S-1-5-21-357043131-537017027-1947940980-1289
    ## MySid prints = PySID:S-1-5-21-357043131-537017027-1947940980-1289
    ## I need this , I believe this is a hex string of the SID

      Re: Converting binary sid's to a hex string

      You can use the binascii module to convert the raw
      bytes of the sid to hex.

      binascii.b2a_he x(buffer(MySid) )

          Thx Roger, I have been off line for a few days. I am sorry not to reply
          earlier. I will try this, but I am not sure what "buffer" does ( I am a
          newbie to python).
