Copy/paste of relevant bits


Here's how you make freeradius check a user/password combo against a Kerberos server, and authorize against your LDAP backend---stick this in your radius.conf:

  modules {
    krb5 {
            keytab = ${confdir}/radius.keytab
            service_principal = radius/radius.example.com
    }

    ldap {
            cache = no
            server = "ldap"
            identity = "uid=freeradius,ou=Accounts,dc=example,dc=com"
            password = secret
            basedn = "dc=com"
            filter = "(krbPrincipalName=%{User-Name})"
            base_filter = "(objectClass=radiusprofile)"

            tls {
                    start_tls = no
                    # tls_cacertfile        = /path/to/cacert.pem
                    # tls_cacertdir         = /path/to/ca/dir/
                    # tls_certfile          = /path/to/radius.crt
                    # tls_keyfile           = /path/to/radius.key
                    # tls_randfile          = /path/to/rnd
                    # tls_require_cert      = "demand"
            }

            default_profile = "uid=freeradius,ou=Accounts,dc=example,dc=com"
            profile_attribute = "radiusProfileDn"
            access_attr = "dialupAccess"

            dictionary_mapping = ${raddbdir}/ldap.attrmap

            ldap_connections_number = 5

            groupname_attribute = cn
            groupmembership_filter = "(|(&(objectClass=GroupOfNames)(member=%{Ldap-UserDn}))(&(objectClass=GroupOfUniqueNames)(uniquemember=%{Ldap-UserDn})))"
            #groupmembership_attribute = radiusGroupName
            timeout = 4
            timelimit = 3
            net_timeout = 1
            # compare_check_items = yes
            # do_xlat = yes
            # access_attr_used_for_allow = yes

            # set_auth_type = yes
    }
  }

This assumes you've added the correct radius schema (ships with freeradius, IIRC) into your LDAP directory, and it should point you in the right direction---I don't do 802.1X, but I do use this config to handle other kerberos-via-radius access control scenarios, and it's been running in production for a while now. Obviously, users are logging in with their full kerberos principals (rather than just usernames).
