Delete pending users in ADSync

Hi. I’ve got a question about deleting pending users from ADSync queue.If I could believe IBM there should be a button in the MMC at windows server side (http://www-1.ibm.com/support/docview.wss?uid=swg21232705).

But I didn’t find any Button “Register users and groups now” in the ADS-MMC. Could anyone give me a hint for this?

Thanks
