For accounting replication your best choise is radrelay. For failover, just use
a failover section in radiusd.conf
session{
redundant{
sql1
sql2
}
[...]
}
authorize{
[...]
redundant{
ldap1
ldap2
}
}
We have a similar setup working just fine in the Greek School Network (two
radius servers, serving different regions but keeping full accounting).
