FreeRADIUS on maintenance mode? Open authentication.

[Antonio Fernández Pérez]

Hi everybody:

I would like to know if there are some option to adjust in FreeRADIUS
configuration to allow open authentication from all users.

I have to make some maintenance tasks on MySQL and I don't want to
interrupt the service. My objective is prevent alter all hotspot
configurations (NASes) disabling RADIUS server.

I hope your advices.

Regards,
Antonio.
