  1. I am having the exact same issue, however I can not find the bugs referenced in your post. It’s pretty annoying too, when in 10.4.x it worked perfectly.

  2. You can’t see others’ bugs (unless you are Apple), but you can list others’ bugs in your own bug report to help let Apple know that you are having the same problem.

  5. Another work-around, given that the “macAddress” attribute is not actually being used: use ADSIEDIT to change the “lDapDisplayName” for the “macAddress” attribute to something like “macAddress-CHANGED” or “macAddress-workaround” or whatever.

    If an ldap query references a non-existent attribute, it will just ignore it immediately, so no delay for lookups. We have the Mac issue, as well as the exact same issue with another application, and since neither is actually using the attribute in question (and no other app is referencing the attributes, either), renaming solves our issues.

    The one caveat being that you have to remember/document that this change was made, or you will have to track it down at a later date (if ever) if the macAddress attribute is ever actually needed at some point.

    USE WITH CAUTION!
    Use ADSIEDIT.MSC to edit “macAddress” in the “Schema” container, changing the “lDapDisplayName” in the properties for “macAddress” to something different.
    You have to be in Schema Admins, and you have to do this on the domain controller with the Schema Master role, and changes have to be enabled.

    Here’s a nice, succinct reference to changing the AD schema:
