FreeRadius Erro ao ler / etc / freeradius / huntgroups

Question

Configurei o freeradius para usar o sql, tudo estava funcionando bem, eu estava fazendo alguns testes com os usuários e, de repente, não consigo iniciar o depurador devido a esse erro:

rlm_preprocess: Error reading /etc/freeradius/huntgroups
/etc/freeradius/modules/preprocess[13]: Instantiation failed for module "preprocess"
/etc/freeradius/sites-enabled/default[88]: Failed to load module "preprocess".
/etc/freeradius/sites-enabled/default[69]: Errors parsing authorize section.

Eu nunca toquei nos arquivos preprocess ou huntgroups ... estou perdido agora !!

Alguém sabe alguma coisa sobre isso?

Editar

• Poderia ser possível que o problema seja sobre permissões?

• Eu faço um backup da pasta freeradius e faço:

  chown -R freerad:freerad freeradius/

Tudo funciona agora, mas não estou muito confortável com isso ...

• Alguém pode me dizer quais são as permissões certas para esta pasta e seus arquivos?

Estou pensando em remover e instalar novamente para evitar mais problemas ...
