817379 has some flaws. If you have an invalid configuration and then make the change it states, the invalid configuration comes across with it.
Furthermore, SSL is not turned on or off. You have made the common mistake of thinking that require SSL turns the setting on and off. It does not. With require SSL disabled, you can still use SSL.
What you have to do is reset everything, turning off FBA etc, then do the directory creation. After that you can turn fba back on.
