UCS LDAP and FreeRadius Disconnect

Hello All,

I have had issues battling with authenticating (wired and wireless users) with the in built Freeradius. I configured my switch IP on /etc/freeradius/clients.conf and also configured ports /etc/freeradius/radiusd.conf and I have done the radius configuration on the switch.

Whenever a client (supplicant) tries to authenticate, it fails. I get the below error:

Hi,

have you already verified your settings with the information provided in RADIUS.

There is also a mention of the CLI-tool univention-radius-check-access which might help.
