get attributes from multiple AD domains

I follow up this link to set up freeRADIUS talk to AD, http://wiki.freeradius.org/FreeRADIUS_Active_Directory_Integration_HOWTO   It can work and can get VLAN attribute from AD through LDAP module (ldap_search). But we need to support 2 AD domains. NTLM_auth can work in multiple domains. But we can not get attributes from multiple domains. Anyone can give me some advice?   Thanks. John. ___________________________________________________________ 好玩贺卡等你发，邮箱贺卡全新上线！ http://card.mail.cn.yahoo.com/
