You will need to setup two (or more) LDAP directory configs in the modules/ldap config.

AD's LDAP interface isn't able to query inter-domain.  So you need to setup a LDAP connection per unique domain.

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.
John
