I've installed freeradius and other packages on a vanilla amazon ec2
instance and am trying to get the rlm_perl module working. Ultimately the
authenticate function in the perl script is not being run. Here are the
details.
Running:
Amazon Linux AMI release 2012.03
Install:
$ sudo yum update
$ sudo yum install freeradius
$ sudo yum install freeradius-perl
$ sudo yum install freeradius-utils
Configuration files:
/etc/raddb/modules/perl:
perl {
#
# The Perl script to execute on authorize, authenticate,
# accounting, xlat, etc. This is very similar to using
# 'rlm_exec' module, but it is persistent, and therefore
# faster.
#
module = /etc/raddb/example.pl
...
}
/etc/raddb/sites-enabled/default:
authorize {
...
perl
...
}
authenticate {
...
perl
...
}
accounting {
...
perl
...
}
rlm_perl files:
/etc/raddb/example.pl:
# Function to handle authorize
sub authorize {
# For debugging purposes only
&log_request_attributes;
print "authorize!!!";
# Here's where your authorization code comes
# You can call another function from here:
&test_call;
return RLM_MODULE_OK;
}
# Function to handle authenticate
sub authenticate {
# For debugging purposes only
# &log_request_attributes;
print "authenticate!!!";
...
Testing:
$ radtest test test localhost 0 testing123
Sending Access-Request of id 154 to 127.0.0.1 port 1812
User-Name = "test"
User-Password = "test"
NAS-IP-Address = 10.111.61.150
NAS-Port = 0
rad_recv: Access-Reject packet from host 127.0.0.1 port 1812, id=154,
length=20
Server output:
$ sudo radiusd -X

Questions:
1/ Request comes in and authorize is being called within rlm_perl. The
print statement is not outputting on the server side?
2/ How does Auth-Type get set? I've read a bunch of forum threads and it
looks like best practice nowadays is to let the server figure it out and
not set it explicitly in /etc/raddb/users, however it isn't being set.
Suggestions?
Cheers and thanks.
