Hi everyone,
I have some project to deploy Extreme NAC server and the client is bind user via AD (Active Directory) using NTLM authentication. I have configured AAA configuration on NAC for AD and tested users (via wireless) on NAC and it seems error state description "The authentication request was rejected due to NTLM authentication error: : Reading winbind reply failed! (0xc0000001)" and reason "Rejected by NTLM authentication". Please advice for this problem. Thank you.
