I have customer planning to deploy 802.1x in their wired network.
1. They are using certificate, username and password to authenticate.
2. Unauthorized user will be assigned to Guest Vlan with limited access to the network.
3. The problem is, when the certificate is expired, user wont be able to authenticate to the network.
4. How to allow user to renew the certificate when then dont have access to their network? Is there any work around?
