vi ldap

In the ldap section change the following fields. In my example I stall radius on the same machine as the ldap server so I am going to connect to localhost. The following config is not the complete config, only the changed part! <code> ldap {

      server = "localhost"
      port = 389
      identity = "cn=manager,dc=helux,dc=nl"
      password = mypass
      base_dn = "dc=helux,dc=nl"

      update {
              control:Password-With-Header    += 'userPassword'
              control:NT-Password             := 'SambaNTPassword'
      }
      user {
              access_attribute = "dialupAccess"
              access_positive = yes
      }

}
