Freeradius , AD and Mikrotik Integration

hello .i really need help .i have a Microsoft Active Directory in my network as a user database , and i installed freeradius as my radius server for wireless users and i have mikrotik router which i implement Nat ,Qos and Queue for bandwidth management .i integrate my freeradius with Active Directory so wireless user can authenticate via Active Directory. but my problem is how can i send user attributes to mikrotik for limiting RX and Tx bandwidth while users are not in Freeradius user file . how can i tell mikrotik to create a queue for that user which authenticates via Active Directory. thank you
