Accept user if his account expired

hello I am using freeradius v3 . I want when expired user trying to access his account the freeradius will send accept packet with new ip pool for example 'expired ' I am using this code in authorize section expiration{ userlock = 1 } if(userlock){ # Let him connect with EXPIRED pool in reply ok update reply { Reply-Message := "Your account has expired, %{User-Name} / Reason: DATE LIMIT REACHED / " Framed-Pool := "expired" } } but user still get reject , without get new ip pool I tried to insert that same code in to Post-Auth-Type REJECT section the users rejected but get new ip pool where is my error thank you
