Enabling "perl" module breaks FreeRadius

8 Apr 2022

      Hi,

On Debian 11:

   1. Add NetworkRadius Debian 11 repo
   2. Install Freeradius packages (3.0.25)
   3. Create required EAP certs in certs dir
   4. Run freeradius -X with vanilla default config. It runs OK
   5. Just enable perl module with "ln -s ../mods-available/perl perl" in
   mods-enabled directory
   6. Run freeradius -X, it no more runs, gives error any dictionary item
   it sees while initializing remaining modules.

Is this a known bug? Any idea why enabling vanilla perl module breaks
dictionary attributes?

Regards,

Rahman
