dovecot - Aug 2006 - dovecot SASL as auth backend to exim?

hi,

i'm running dovecot branch_10 cvs on OSX 10.4.7 w/ exim 4.63.

i'd like to use Dovecot's SASL as an auth backend to exim, instead of 
Cyrus-SASL.

@ dovecot's sasl page:

   http://wiki.dovecot.org/Sasl

i know there's a patch against exim 4.43:

   http://www.exim.org/eximwiki/AuthenticatedSmtpUsingDovecot

that, purportedly, enables EXIM to use dovecot's SASL as an auth backend.

questions:

(1) with 'recent' updates to both dovecot/exim, is that patch still
required?
(2) if so, is that patch still viable/safe against 4.63?
(3) can anyone provide a _specific_ example of the exim config(s) (Makefile, 
Router, Transport) they're using to 'make it work'?

i've asked this question @ exim list, but, other than a 'why would you
bother?'
and a  'good luck with your efforts', no "joy" so far ...

thanks,

richard

I guess so

Well it applies cleanly (after substituting "exim-4.63" for
"exim-4.43")
and seems to build OK (on Solaris 10)

No, but I'd try what was suggested in the "authenticators"
section;
something like :-

begin authenticators

ntlm:
        driver = dovecot
        public_name = NTLM
        server_socket = /var/authentication_socket_path
        server_set_id = $1

... etc.
