Also includes some changes for jessie's version of FreeRADIUS 2 (was
previously a custom version).
Besides the move to a subdir the config files were adapted for 3.0.
The rlm_sim_files module was removed with FreeRADIUS 3 and Debian's
package of FreeRADIUS 2 does not ship it, so we now replicate it using
the files module (via users file, which is actually a symlink to
mods-config/files/authorize in the default installation of FreeRADIUS 3).
Another approach was tried using rlm_passwd, however, that module does
not read binary/hex data, only printable strings, which would require
changing the triplets.
For 2.x a hack in the site config is necessary to make the attributes
available to the EAP-SIM module.
While we could continue to use FreeRADIUS 2.x that branch is officially EOL.
So instead of investing time and effort in updating/migrating the patches to
FreeRADIUS 3.x (the module changed quite significantly as it relies solely on
the naeap library in that release), for a protocol that is superseded anyway,
we just remove these scenarios and the dependencies. Actually, the
complete rlm_eap_tnc module will be removed with FreeRADIUS 4.0.
