We are experiencing an issue with a wireless user in SSID "AIRLOCK". The user can authenticate successfully from the corporate laptop, however, the account is being repeatedly locked in Active Directory due to continuous authentication failures coming from a different MAC address. The behavior is the following: - Successful authentication occurs from MAC: FC-B3-AA-AA-14-8C (Windows 10 device) - Continuous failed authentication attempts occur from MAC: 42-E0-36-74-EE-35 - These failed attempts happen approximately every minute - The account gets locked automatically due to AD lockout policy We have already: - Reset and validated user credentials - Removed and reconfigured WiFi profiles - Verified no MAC randomization is enabled on the known devices - Confirmed correct device connects successfully Despite this, the issue persists.
