Nope, and I wouldn't do it myself either. However the person
did not ask for advice, only how to actually accomplish that
particular configuration.

--> Do you actually have this working in production? I have never configured it this
way and I do not think that I would recommend using different AAA protocols to back
each other up. The first reason is related to the adminstrative burden that this would
entail - since the authorization and accounting formats are different on tac+ and
radius I think that verifying that each change made to the primary policy database (in
tac+) is reflected completely and properly in the secondary policy db (radius) would
be a considerable task. Add to this the fact that tac+ allows user attributes to
override group attributes when some radius implementations do not and the fact that
some parameters have different syntax in the protocols (ie. raccess vs. rtelnet) and I
think that this could be a rough ride.
-->
--> There is another difference in the two protocols that may cause headaches WRT
authorization - tac+ completes authentication and authorization in discrete steps,
radius typically caches the authorization attributes obtained during the
authentication phase. What happens when the user is authenticated via the radius
failover option and then authorization is needed - are the cached attributes from the
authentication used, or is there another communication with the radius server during
which the user is prompted for the authentication information (ie account and
password)?
