This is very good news, as it deals with a common requirement without
having to configure saslauthd.

One suggestion following a very quick scan of the code: I think it
would be worth bringing the warning about turning off TLS checks
into the manual page.

It is worth noting that this overlay raises issues similar to those
raised by the contributed adpwc/extpwc module - see ITS#5042. In this
case the access to AD is via LDAP rather than Kerberos, but most of
the arguments are similar. In particular, there is no reason for this
to be AD-specific and it should be easy to adapt it to authenticate
against any [collection of] remote LDAP servers.
