Why not? Let's try it out.

Configure 802.1x with radius and enable debug radius. Note the service
request name. Go to the TACACS interface in ACS and add the a custom service
with the name that we saw in the radius debug.

Go to the user profile and add the three attributes that is required for
802.1x under the TACACS new custom profile that we have added. If the IOS
accepts the AV, the it would work.
