Sidhistory issue with 7 mode system

Hi All,

We have used ADMT to miragate sidhistory between domains and we have windows file servers that are succesfully using sid history to give user access to fileshares, however we cannot get 2 netapp systems using cifs to function by allowing users  access to files using sid history. if we add users explicitly to the cifs fileshares from the other domain through the trust it works fine. otherwise its just access denied.

Any thoughts will be gladley accepted.

Thanks
