Hi, My FreeRadius is working fine, my wireless clients are able to authenticate with username and password from the /etc/raddb/users file and dynamic vlan assignment is working fine too. Need to now configure to restrict a user to get authenticated only from a single mac address, so the dynamic vlan assignment is restricted to that user only from its authorized mac address. Please help. I tried following the How-to guide but have not been able to get it working. please help. I have attached my configuration files for your reference, please let me know if how to go about doing it. http://freeradius.1045715.n5.nabble.com/file/n4297874/authorize_macs authorize_macs http://freeradius.1045715.n5.nabble.com/file/n4297874/default%5Bsites-availa... default%5Bsites-available%5D http://freeradius.1045715.n5.nabble.com/file/n4297874/eap.conf eap.conf http://freeradius.1045715.n5.nabble.com/file/n4297874/files files http://freeradius.1045715.n5.nabble.com/file/n4297874/policy.conf policy.conf http://freeradius.1045715.n5.nabble.com/file/n4297874/radiusd.conf radiusd.conf http://freeradius.1045715.n5.nabble.com/file/n4297874/users users -- View this message in context: http://freeradius.1045715.n5.nabble.com/MAC-Address-and-Username-Binding-on-...
