freeradius force authentication reject for some users?

[Eero Volotinen]

Hi List,

I am using radius based otp ubikey authentication like this:

http://www.linuxforu.com/2011/08/setip-two-factor-authentication-using-openotp/

is there nice way to reject some users? just want to reject radius
authentication for user foo. this user has account on otp, but want to
reject all authentication attempts on radius?

is there option to force-reject-authentication for user foo2,foo3? on
freeradius?

thanks,
