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. -j
