https://community.cisco.com/t5/network-security/troubleshooting-port-authentication-with-nps-error-code-22/m-p/5129111#M1113509 <P>Hello everyone,<BR /><BR />I have little expertise in network security and work for a small company. I need to configure port authentication for a <SPAN>SF550X-24P 24-Port 10/100 PoE Stackable Managed Switch</SPAN> with firmware version 2.5.9.54.<BR /><BR />What I learned is that I need to configure a RADIUS server for which I used our Active Directory Domain Controller and installed NPS server role. After setting up the configuration and enabling "Auto" and "Web authentication" for a specific port I tested the connectivity by logging in with credentials from a test AD User. After not getting permitted into the network, I looked into the event logs on my windows server and saw error code 22: "The provided EAP Type couldn't be processed by the server".<BR /><BR />I tried the following things, since I was made to believe this had to do something with a faulty TLS Handshake between Switch and Server. I made sure to create a certificate for the purpose of clientauthentication for my NPS and also installed the same certificate on my switch. After doing that, I unfortunately got the same error log telling me that the wrong EAP type was used. On the NPS I have configured every possible option for authentication methods just so I can debug the problem. Do I need to configure anything else on my switch? Because if so, I have not found a method to do so yet, because even in the documentation, there is only mentioning of "EAP" and nowhere anything according to other EAP types or methods.<BR /><BR />I also got told that the "client" chooses EAP type so I have to configure my own computer? I tried configuring EAP but Windows 10 does not let me do that through GUI options that easily for LAN connection.<BR /><BR />Does anyone have any idea what the issue could be here?</P> Wed, 12 Jun 2024 15:28:44 GMT jasinkadrioski 2024-06-12T15:28:44Z https://community.cisco.com/t5/network-security/troubleshooting-port-authentication-with-nps-error-code-22/m-p/5129111#M1113509 <P>Hello everyone,<BR /><BR />I have little expertise in network security and work for a small company.
