Hello,
I wanted to use the FreeRadius package included in Ubuntu 12.04.2 LTS
(GNU/Linux 3.2.0-49-generic x86_64) to do SMS OTP password. In order to
do that I need to load perl code into FreeRadius which fails with the
following error on a fresh installed system:
(1) FreeRadius does not recognize symbol from perl module
sudo apt-get install freeradius libauthen-krb5-simple-perl
sudo cat > /etc/freeradius/sites-enabled/perl <<EOF
authenticate {
perl
}
authorize {
update control {
Auth-Type := perl
}
preprocess
}
preacct {
preprocess
acct_unique
suffix
}
accounting {
detail
radutmp
attr_filter.accounting_response
}
session {
radutmp
}
EOF
sudo cat > /etc/freeradius/example.pl <<EOF
use Authen::Krb5::Simple;
EOF
root@ubuntu64:~# sudo /etc/init.d/freeradius restart

...done.

Can't load '/usr/lib/perl5/auto/Authen/Krb5/Simple/Simple.so' for module

at /etc/freeradius/example.pl line 1
Compilation failed in require at /etc/freeradius/example.pl line 1.
BEGIN failed--compilation aborted at /etc/freeradius/example.pl line 1.
...fail!
In order to resolve that issue the FreeRadius version need to be upgradred.
However I tried to rebuild from source because I saw a similar bug before which
got resolved by rebuilding the package after a perl security update:
(2) Freeradius does not build from source.
sudo su -
apt-get build-dep freeradius
apt-get source freeradius
cd freeradius-2.1.10+dfsg/
debian/rules binary
And it fails:

For the second issue I saw that there was a bug report which was closed because
it was not reproducible. For me it is, I reproduced it on a system setup from
scratch. I installed your ssh key on the system so that you can troubleshoot the
problem.
ssh -l yolanda -p 4001 infra.gmvl.de
You can get root by issueing 'sudo su -'. I disabled the password prompt.
You can also set you a password by 'sudo passwd yolanda' if necessary.
The system has full internet access.
Please let me know if I should file a bugreport for (1) and/or reopen the
bugreport for (2).
Howto reproduce the build bug:
- Install a fresh Ubuntu in the packet selection only select ssh
server
- Execute the commands mentioned above.

As Alan has mention on the bug 1090365 in launchpad, is is easily fixed
by applying the following patch:

So I wonder why the build problem was not fixed?
I really would like to see that both issues get fixed. That way the out of the
box FreeRadius packet gets usuable and someone does not need to recompile the
package. Also I do not understand why Debian and Ubuntu does not have the
current version of the 2.2.x branch. It looks like the package is no longer
maintained. I also do not see a current version in SID (for Debian and Ubuntu
that is). So I wonder what is going on here?
So for now I'm stuck with compiling FreeRadius by myself for
Debian/Ubuntu. Has someone updated Debian packages somewhere?
Cheers,
Thomas
