Nas Duplicated authentication attempt

giuseppe.fiorentini — Sun, 10 Mar 2019 20:49:19 GMT

Hi I'm working with XP sp2 and ACS 3.2(3) and wireless LAN. I use PEAP-MSCAHPv2 on my client and authentication through a windows database W2003server.

If I start regulary my client everything is ok, both machine and user authentication, but if for any reason I lose the connectivity I have the error "NAS duplicated authentication attempt" on ACS's logs.

Is there anyone that can help me? All the certicates are ok, I've already checked.

Thanks a lot.

Stefano

Hi Stefano,

I had this problem in one client and the problem is in ACS 3.2(3)The definitive solution is install ACS 4.0(1.27)

I made it and all problems disappear

The bug for this case is CSCeg01533 and the TAC case n? is K25478174
