I guess the part I don't get here, is that this setting does not
disable anonymous access to rootdse it just requires, as far as I
understand, that TLS or some security be used for the connection.

I currently have minssf set to 56 and am able to anonymously bind and
obtain the rootdse.

I understand there may be troubles along the way but wouldn't setting
this as a default be a "good" thing to aim for?
