[Samba] ldap server require strong auth = no

[Gregory Sloop]

I, perhaps amazingly, have FreeNAS working properly now.

One of the issues was that I needed to set ldap server require strong auth = no
on the Samba DC.

So, what are the implications of doing that?
Does authentication happen over LDAP, or just user/group enumeration?

Is there a wiki page that covers that somewhere?
[And how does Windows not suffer from the same security issues, if it's obviously not using signed/sealed LDAP?]

TIA
