As far as I can tell:

  1. Figure our the SQL queries that return the "check/reply" and group 
items you want for the values in the DHCP packet
  2. Configure those queries on an instance of the SQL module
  3. Use the config:

dhcp ... {
   ...
   # do radcheck/radreply
   sql.authorize
   ...
   # do radacct-like behaviour
   sql.accounting
}

The latter is necessary because "dhcp" blocks are post-auth blocks 
internally, so you need to specify that you want "authorize" not 
post-auth behaviour.

Dynamic IP assignment might require the sqlippool module; the server 
comes with examples for this.
