Problems with callback and SecureID

Users can call to my 3640 and, after it authenticates them with AAA RADIUS, it makes a callback and it works fine. I need to authenticate the users with RADIUS and SecureID. The initial authentication works fine, but when the router calls back the koken has changed and the user is invalid...

I already have configured this in the asyn group:

ppp authentication pap callin

but the router still tries to authenticate the call out .

I see many people has this problem,,,, is any solution???

I use analog lines and this is the sh version:

Re: Problems with callback and SecureID

Sounds like you need to enable token-caching on the ACS server, this way it'll keep track of the old tokens for a defined period of time and automatically authenticate the callback. This is also used with ISDN/multilink calls for bringing up the second channel a short time after the first.

Under the Group settings on ACS, there's a section for Token Card's. Select Duration and say, 2 minutes and see how that goes. You may need to play with the time depending on your setup.

More information on token caching is available in the online docs.
