IP assignment based on AD group

Hi, I currently have vlan assignment based on ad group working flawlessly for my wireless clients. Now I want ip assignment, is it possible? I tried to achieve that with the ippool module but I think I am missing something. How should I configure the wlc or the dhcp server? mods-enabled/ippool ippool professores-cstsi {         filename = ${db_dir}/ippools/professores-cstsi.ippool         range_start = 172.17.10.1         range_stop = 172.17.10.20         netmask = 255.255.0.0         cache_size = 20         ip_index = ${db_dir}/ippools/professores-cstsi.ipindex         override = yes         maximum_timeout = 0 } users DEFAULT LDAP-Group == "test", Pool-Name := "professores-cstsi" Thanks.
