Quite strangely, i'm geting the following "error" message:

Aug  4 19:09:26.529: ppp217 PPP: Phase is FORWARDING, Attempting Forward
Aug  4 19:09:26.533: AAA/AUTHOR (0xF6): Pick method list 'VPDN-AAA' - FAIL
Aug  4 19:09:26.533: AAA/AUTHOR (0xF6): Pick method list 'VPDN-AAA'

Aug  4 19:09:26.541: uid:217 Tnl/Sn 50748/295 L2TP: Create session

but it works !!!!

PS: VPDN-AAA is my vpdn aaa method.

I'll give it some more tests and see if there are any other problems.
