freeradius 3.0.13 LDAP - reply custom Vendor Specific

Hi I have connected freeradius to freeIPA's ldap ( https://www.freeipa.org/page/Using_FreeIPA_and_FreeRadius_as_a_RADIUS_based_...). I try to authenticate IPMI server trough freeradius but it require two custom attributes (Vendor Specfic) ie for admin H=4 and I=4. How should I configure freeradius to reply for every request with custom above attributes (without adding them in the ldap schema) I found here http://wiki.freeradius.org/modules/Rlm_ldap that I should add for example: radiusReplyAttribute: Cisco-AVPair := "ip:addr-pool=dialin_pool". Unfortunately I completely dont know where in raddb/mod-avaliable/ldap should I place similar line. Any help would be very appreciated Regards, Paweł
