provide DAC and NAC to one host

[MichaelLeung]

hi list

here is an example of one of my client.conf and the virtual-server
------------------------nas-----------------------
client devices {
         ipaddr = 192.168.1.1
         proto = *
         secret = testing123
         require_message_authenticator = no
         nas-type = other
         limit {
                 max_connections = 16
                 lifetime = 0
                 idle_timeout = 30
         }
         virtual_server = devicemanager
}

----------------------------virtual server----------------------
server devicemanager {
authorize {
         Use_Auth_Ladp
         filter_username
         disabled
devicemanager_check
         ldap
         pap
}
authenticate {
         Auth-Type PAP {
                 pap
         }
         Auth-Type CHAP {
                 chap
         }
         Auth-Type MS-CHAP {
                 mschap
         }
         digest
         Auth-Type LDAP {
                 ldap
         }
         eap
