It is a bit like setting this:
If they say 'just use SSL', then the allow_sasl_over_tls part of that
option is to address this issue:
We (and likely they) don't support the channel bindings (patches
welcome!), but the protocol flaw (no link between the SSL and the
NTLM/Kerberos handshake inside) is the one we are trying to avoid.
The manpage is vague because we fixed our implementation before they
did the above.
