Hello to all.

Try moving the user1 line before the DEFAULT (and reverse the 'fall through' specifications)....

Thank you Charles for your advice.
But the problem in this case is: If I move the user-lines before
DEFAULT, freeradius tries to authenticate with any other Auth-Method,
exept MOTP.

[...]
rad_recv: Access-Request packet from host 192,168.82.41 port 33260,

        User-Name = "user1"
        User-Password = "aa8809"
        NAS-IP-Address = 192,168.82.41
        NAS-Port = 0

+- entering group REJECT
        expand: %{User-Name} -> user1
 attr_filter: Matched entry DEFAULT at line 11
++[attr_filter.access_reject] returns updated
[...]

So, it seems that I have to use the DEFAULT-line at first to use MOTP as
the default Auth-Type.

But now some new good news: After changing the module configuration in
radiusd.conf to

exec motp {
  wait = yes
  program = "/usr/local/bin/otpverify.sh %{User-Name} %{User-Password}
%{control:Secret} %{control:PIN} %{control:Offset}"
  input_pairs = request
  output_pairs = config
}

...tested with radtest, everything works fine (thank you, Ivan) :-)

auth: type "MOTP"
+- entering group MOTP
        expand: %{User-Name} -> user1
        expand: %{User-Password} -> eaec5f
        expand: %{control:Secret} -> 143a5c6fa125ac1f
        expand: %{control:PIN} -> 1234
        expand: %{control:Offset} -> 0
Exec-Program output: ACCEPT
Exec-Program-Wait: plaintext: ACCEPT
Exec-Program: returned: 0
++[motp] returns ok



What a nice adventure...

Now, I have another problem with mod_auth_radius. But this is another story.

Best regards,
Stefan
