AD authentication failed

pavelboruta

Hello,

we are using nxc2500 with NWA5123-ac and I want to set up the AD authentication on one SSID. I did everything according to manual, AD configuration validation is OK, but when I fill login on client, while Iam connecting on this SSID, error message appear - unable to connect, and in the Zyxel logs is this message: blocked by auth failed,reason 23.. I already upgraded firmware on the last version (6.1), but its still not working.. any tips??

Thanks a lot!

Hi @pavelboruta,

NXC2500 is EOL, so the support we can provide is limited.

Please reference this FAQ to check if your configuration is correct.

If correct, please check the AD server's log to see if the AD server received authentication and why it failed.
