I would like to ask 1 question about machine based authentication on 802.1x.
1.We are deploying 802.1x on wired user.
2.Some user are using machine based authentication in order to authenticate their port.
3.However, after the user password expired, the user need to change their password and then the machine are unable to authenticate. The error i got is "External DB user invalid or bad password". Then switch assign the user to Guest Vlan
4.But, once i plug out the cable and plug in back the UTP cable after the user login, the switch will assigned the user to proper VLAN.
5.User wont be able to access their share drive n etc since the guest vlan only have access to the internet.
5.Anyone have any idea what is happening? It seems that the machine is sending the old password during authentication process to the ACS.
Anybody can shed a light to me. Thanks.
