Another interesting point is: do I right understand that I need to restart freeradius every time when I correct users file? Is is complicated for me, what is other way? Maybe store MAC's in LDAP or SQL database?

Yes, if you store details in users file you will need to restart for new entries to take effect. If you store them in sql or ldap you can manage them independantly of freeradius. Ivan Kalik Kalik Informatika ISP
