[RadiusNT] Re: radius authentication problem after upgrade to 12.1(3)

I found the problem using debugging however I do not quite
understand why this is now happening.

Debug shows attribute "idletime" failed. Looking at the
radius docs the attribute "idletime" is a tacacs attribute not
a radius attribute. My debug files of the radius server do not show
this attribute but the correct radius attribute "Idle-Timeout".

If I remove the radius attribute "Idle-Timeout" from my dial-in
profile on my radius server the AS5300 is again working with with
my radius server.

Debug of AS5300:
-------------------

09:34:00.093: Se2:27 AAA/AUTHOR/LCP: Processing AV service=ppp
09:34:00.093: Se2:27 AAA/AUTHOR/LCP: Processing AV idletime=1200
09:34:00.093: Se2:27 AAA/AUTHOR/LCP: idletime failed
09:34:00.093: Se2:27 AAA/AUTHOR/LCP: Denied

Debug of radius server:
-----------------------

Sending Ack of id 240 to d418c803 (as5300_10)
Framed-Protocol = PPP
User-Service = Framed-User
Port-Limit = 2
Idle-Timeout = 1200
Framed-Netmask = 255.255.255.255
Session-Timeout = 0
Framed-Routing = None

All this worked with 12.04XJ(4). Is my radius server
having a bug or IOS 12.1(3) or am I missing something??
