Security - 802.1x with WLC and AAA server
When implementing security on a WLC using IEEE 802.1x and an AAA server for passwordless access, it is possible to use multiple AAA servers for this purpose.
Windows Active Directory is one option, but it is not the only option to use 802.1x and password-less access. You can use various other platforms that leverage the RADIUS protocol including freeRADIUS , Cisco ISE, TACACS+, and Aruba ClearPass to name a few. These servers can integrate with various directory services, not just Active Directory.
The key is to have a server that supports EAP-TLS, which is the protocol used for certificate-based authentication in 802.1x. This allows the server to validate the client’s certificate to provide password-less access.
So, you have several options to choose from depending on your network infrastructure, budget, and specific requirements.
