Alekz just asked about the problem with value limits and reading from AD (query) and I have another question similar to that.

How do you do to provision large groups (>5000 members) to AD?

There seems to be a fuzzy limit of about 5000 members where AD responds with a server busy error (the driver respond with a
retry status).

Reading MS knowledgebase say that you should split transactions with a large number of operations (large number is not clearly
defined) into multiple transactions.

Best regards,
