Yeah.

Won't work right now.

You'll get quotaBytes set to quotaBytes's value, which won' t do anything useful. %$ gets expanded to quotaMessages's value in both cases.

user_attrs {
  home = %{homeDirectory}
  quota_rule = *:bytes=%{quotaBytes}
}

And of course you would be able to mix and match the %{whatever-ldap-value} attributes.
