Here is the smoking gun, so to speak:

3w4d: As2/50 AAA/AUTHOR/IP: authorization failed

And if you look at what is being authorized/downloaded from the AAA server:

3w4d: As2/50 AAA/AUTHOR (736691766): Post authorization status = PASS_REPL
3w4d: As2/50 AAA/AUTHOR/IPCP: Processing AV service=ppp
3w4d: As2/50 AAA/AUTHOR/IPCP: Processing AV addr=2.1.9.2
3w4d: As2/50 AAA/AUTHOR/IPCP: Processing AV outacl=internet
3w4d: As2/50 AAA/AUTHOR/IPCP: Processing AV inacl=160
3w4d: As2/50 AAA/AUTHOR/IPCP: Authorization succeeded

I suppose the problem could be that you don't have access-lists 160
or internet defined on the 5350.  Is that possible?
