Mac-Auth or 802.1x

[Alpers, Andreas]

Hello,

My experience with Freeradius is still in the beginning. My requirements in the first step are not very high. 
I want to configure Freeradius so that users can be authenticated via 802.1x or via MAC-Auth.

I followed these instructions exactly:
https://wiki.freeradius.org/guide/mac-auth#mac-auth-or-802-1x

Unfortunately, it does not work. I have created a username and password and also entered a Mac address in the file. 
But neither the user nor the Mac address work. I always get a reject, although it should work according to the instructions.

I get the following answer when I run radtest:

radtest andreas andreas123 127.0.0.1 1812 testing123
Sent Access-Request Id 123 from 0.0.0.0:51323 to 127.0.0.1:1812 length 77
        User-Name = "andreas"
        User-Password = "andreas123"
        NAS-IP-Address = 127.0.1.1
        NAS-Port = 1812
        Message-Authenticator = 0x00
        Cleartext-Password = "andreas123"
Received Access-Reject Id 123 from 127.0.0.1:1812 to 127.0.0.1:51323 length 20
(0) -: Expected Access-Accept got Access-Reject


Here are the individual files. I am very grateful for any help.



/etc/freeradius/3.0/mods-available/files:

files {
        moddir = ${modconfdir}/${.:instance}
        filename = ${moddir}/authorize
        acctusersfile = ${moddir}/accounting
        preproxy_usersfile = ${moddir}/pre-proxy
}

files authorized_macs {
        key = "%{Calling-Station-ID}"
        usersfile = ${confdir}/authorized_macs
}

   # The instructions also say here
   # compat = no
   # but if I leave this in, I get an error message and the server no longer starts. Why does this happen?
