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.

authorize {

preprocess
chap
mschap
digest
suffix
eap {
ok = return
}

files

    redundant {
ldap1
ldap2
    }

expiration
logintime
pap

# Autz-Type Status-Server {
#
# }
}

authenticate {

Auth-Type PAP {
pap
}

Auth-Type CHAP {
chap
}
Auth-Type MS-CHAP {
mschap
}

digest

#
#  Pluggable Authentication Modules.
# pam
unix
Auth-Type LDAP {
ldap1
ldap2
}
eap

# Auth-Type eap {
# 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.
