Hi Guys, we are trying to get Free Radius to authenticate our users who
connect through a Cisco Small Business POE switch.
When testing authentication with a shutdown / no shutdown command on
port fa/17 which has an IP phone connected to it we receive the
following errors:
FREE RADIUS :
[ldap] expand: %{User-Name} -> root

However when we try the same test on a port that has a PC connected to
it we do not receive such an error.
The CISCO switch says that we have the wrong user name and the Free
Radius log says access rejected. Why would this only be the case when
a CISCO IP phone tries to authenticate?
The Cisco switch port configurations are exactly the same and are as
follows :
dot1x max-req 1
dot1x reauthentication
dot1x timeout quiet-period 30
dot1x mac-authentication mac-only
dot1x port-control auto
storm-control broadcast enable
storm-control broadcast level 10
storm-control include-multicast
spanning-tree portfast
macro description "no_ip_phone_desktop | ip_phone_desktop"
switchport trunk allowed vlan add 100
macro auto smartport type ip_phone_desktop
What can I try to fix the authentication issues so that all ports are being
successfully authenticated ?
Thanks for your assistance,
Dan
