two ldap servers in my config

Hello Using freeradius 2.1.6, my users are authenticated against the Active Directory. I have a primary and a secondary controller on the network. I wonder if you could specify in the configuration of two ldap servers, when one does not respond due to technical queries are then made my second controller. This is my autenticate section: authenticate { Auth-Type LDAP { ldap } } Thanks Michel ---------------------------------------------- Webmail, servicio de correo electronico Casa de las Americas - La Habana, Cuba.
