Hi,
As i was not able to find the following in the documentation I assume that it’s a bug but may I have overlooked something.
In order to make some additional checks for a RadSec connection, I enabled “check_client_connections” in the listen part and added
Autz-Type New-TLS-Connection {
auth_log
}
in the authorize section in the server block.
And I can see that the Autz-Type gets complied on server start. But the section will only get called if TLS 1.3 was used. For TLS 1.2 it just doesn’t see or call it.
Connection with TLS 1.3

Is that on purpose and not documented or have i overlooked something?
It’s the same behaviour with the source of 3.2.x and the default configuration.
