I know I know but I think I ran into a device that actually _hate_ this attribute for some weird reason.. at least it worked prior to upgrading and now it doesn't .. so at least to exclude this possibility it would be good to be able to remove it without degrading Radiator..

See if this works:

<Client 127.0.0.1>
     Identifier loopback-client
     Secret  mysecret
</Client>

<Handler>
     <AuthBy FILE>
         Filename %D/users
     </AuthBy>

     PostAuthHook sub { my $p = ${$_[0]}; \
         $p->{rp}->{skip_message_authenticator} = 1 \
             if $p->{Client}->{Identifier} eq 'loopback-client'; }
</Handler>

The idea is to see if the request was received from a problematic 
client. If it was, then the reply is tagged with a special flag that 
suppresses Message-Authenticator. This is sometimes needed for odd 
Radius dynauth servers etc. This flag should be considered an internal 
flag and if the need for a configuration option arises then we can 
consider it. However, it should allow you to check if it makes the 
client work again.

Please let me know if you can tell what's the device in question.

Thanks,
Heikki
