Anonymous binding has stopped working

Issue Summary

All of our LDAP sites have started failing to bind anonymously after updating to beta 12. Making them bind as a user works, so that is my temporary workaround, but it used to work fine anonymously (and that would be our preferred choice). I haven't had chance yet to test it on dev to see if its that same, and I am not really sure what would cause it to fail, but the error that the module is displaying is that it failed to bind. I have confirmed that you definitely can still bind anonymously to the servers, so its something the module is doing differently.
