Multiple forests

Hi, We are using freeRADIUS-1.1.6 talk to active-directory (multiple DOMAINs: "A.com" and "sub.A.com"). We use rlm_ldap module Global catalog port to get attributes from ADs. It works fine.   Now a forest(e.g.  "B.com", "sub.B.com" ...) that is trust with domain "A.com". I can not get attributes from forest "B.com".  How to get attribute from forest "B.com" ? Any commnet is welcome.   Thanks.
