multiple ldap servers

[jeff donovan]

Greetings

I'm new to radius but have been reading.

I have a freeradius server running on ubuntu 11, my users file is an ldap 
server which works great. My question is,

how can i search and alternate LDAP server for user credentials ?
If the first LDAP search fails try the next server in line. 

I found some documentation-
* http://freeradius.org/radiusd/doc/ldap_howto.txt  does not mention a second 
server.
*http://freeradius.org/radiusd/doc/configurable_failover explains the redundant 
setup for sql accounting. 

so far I tried adding the second ldap server, it's info is read during module 
load -- no errors. The problem is,.. only one of the ldap systems contains the 
correct info. So one WILL fail and the other will pass. 
with that being said,.. How do i configure my server to Pass if either system 
returns " ok " ? currently it will fail even if one LDAP system returns good.

        }
        
        eap

#                       handled = 1  
#               }
#               if (handled && (Response-Packet-Type == Access-Challenge)) {
#                       attr_filter.access_challenge.post-auth
#                       handled  # override the "updated" code from attr_filter
#               }
#       }
}


Any Assistance would be helpful.
