Configuring free radius to use Active directory service

Hi All, I have some doubts.. 1. How to configure the freeradius1.0.5 version, to support Active directory service for user authentication. For ldap .. we have rlm_ldap module to configure it. Same kind of configuration is there for ADS also ?? 2. Assigning vlan id's to user group is possible ?? rather than configuring each user with a particular vlan id, can we give the vlan id's for the group so that the users part of that group will be assigned with the same vlan. Awaiting for your earliest reply. Thanks, Sumithra. -- "If u look at what u dont have in life, u dont have anything But if u look at what u have in life, u have everything.....!!"
