Here is my virtual server configuration on sites-enabled
server wireless {
                 authorize {
                                preprocess
                                files
                                update control {
                                     Auth-Type := perl
                                              }
                                perl
                        }

                authenticate {
                        Auth-Type Perl       {
                                        perl
                                        }
                             }
                preacct  {
                        acct_unique
                        files
                         }

                accounting {
                        sql_wireless
                           }
                session {
                        sql_wireless
                        } ..............................


And here is the sql.conf file for this sql sttement

        radius_db = "wireless"

        acct_table1 = "radacct"
        acct_table2 = "radacct"


        # Allow for storing data after authentication
        postauth_table = "radpostauth"

        authcheck_table = "radcheck"
        authreply_table = "radreply"

        groupcheck_table = "radgroupcheck"
        groupreply_table = "radgroupreply"

        # Table to keep group info
        usergroup_table = "usergroup"

        # If set to 'yes' (default) we read the group tables
        # If set to 'no' the user MUST have Fall-Through = Yes in the
radreply table
        # read_groups = yes

        # Remove stale session if checkrad does not see a double login
        deletestalesessions = yes
 # number of sql connections to make to server
        num_sql_socks = 10

        # number of seconds to dely retrying on a failed database
        # connection (per_socket)
        connect_failure_retry_delay = 60

        #readclients = yes

      # Table to keep radius client info
        nas_table = "nas"

        # Read driver-specific configuration
