Thanks Phil
I have made the changes to the /etc/raddb/sites-enabled/default that
you described. ie:
authorize {
...
perl
if (ok) {
update control {
Auth-Type = perl
}
}
...
}
authenticate {
...
Auth-Type perl {
perl
}
...
}
It looks like we made some progress...
Here is the new debug:

So now I have a problem in line 92 of the perl script, line 92 is: my
$output = get($url);
here is the whole added bit:
sub authenticate {
my $logfile = "/dev/null";
my $date = `/bin/date`;
chomp $date;
my $url = "http://10.151.4.3:4500/PATRONAPI/" .
$RAD_REQUEST{'User-Name'} . "/" . $RAD_REQUEST{'User-Password'} .
"/pintest";
my $output = get($url);
if ($output =~ /RETCOD=0/) {
`echo "$date : SUCCESS $RAD_REQUEST{'User-Name'} -
$RAD_REQUEST{'User-Password'}" >> $logfile`;
$RAD_REPLY{'Reply-Message'} = "Success";
return RLM_MODULE_OK;
} else {
`echo "$date : FAIL $RAD_REQUEST{'User-Name'} -
$RAD_REQUEST{'User-Password'}" >> $logfile`;
$RAD_REPLY{'Reply-Message'} = "Denied access by RADIUS";
return RLM_MODULE_REJECT;
}
}
I know I'm pushing my luck, but can someone recognize the undefined
subroutine and help me out.
