> You've mentioned a few times that LDAP is not meant for authentication, however the default config that ships with FreeRADIUS has LDAP in  
the authentication section. Could you clear that up a little for me please? (or point me to somewhere it's been cleared up before?) 

 Don't force Auth-Type Ldap.
 
But you will have to use two sql instances - one to store reply info and one to store backup passwords. You can't store passwords in sql (used for reply attributes) and ldap as well.
authorize {
...
sql_reply
ldap
if (notfound | fail) {
    sql_bkp_pass
}
...
}
