    I'm trying to track changes to AD and whenever I run a search like:

    (&(uSNchanged >= lowernumber)(uSNchanged <= hisghestCommittedUSN))

    I get zero results....using ldp/aduc/script

    I am a domain admin, are there any other rights needed to perform this
    search ?

  2. I'm not sure what the second clause really does for you, as that only really
    serves exclude the last object updated on the server.

    Why not start with something like (uSNChanged>=0) and return 10 records and
    make sure that is working. Then, you can start increasing the value and
    such.

    Also, is the typo in the second clause relevant?

    right. yes I have done both. still getting nothing back actually, did:

    (usnChanged >= *) /* is this the same ? */

    and tossed out the upperbound part of the search (I've seen it in other
    places,
    but I agree, it's kind of useless).
    no. that's just pseudocode representation. I've checked my code and even
    inserted actual values to make sure I'm not going crazy (plus, I have use
    strict on and warnings in my perl script so I'm pretty sure i'm covered
    there).

  4. The only other thing I can think of is that the search base or scope is
    wrong (or you didn't bind correctly). I can't replicate your results
    otherwise. usnChanged>=0 returned as many objects as I asked for.

    i've verified the bind and the search scope by changing out the filter
    and getting back the desired results....

    thanks

  6. I have no clue then. I can't repro your results. The only thing I can
    think of is that you are spelling something wrong in the filter.
