Hi, I need to implement MAC-Address filters,every user may have multiple MAC-Address. I'm using freeradius with openldap. Can i use ldap macAddress attribute to make this filters? How does Radius understand this attribute? Are request same modifications to ldap.attrmap, and if so what are the modifications to be made? Thanks in advance Bill Wood _________________________________________________________________ Express yourself instantly with MSN Messenger!
