dovecot - Aug 2008 - Proxy logging destuser

Hi All
 
My first post to the list, so "hello world"!
 
Having searched the list archives and the wiki for an answer to this, I
don't think it is possible. However, let me ask nonetheless...
 
Is it possible for a Dovecot proxy's login process (IMAP and POP3) to
include the "destuser", i.e. the uid used to authenticate to the
backend
IMAP/POP3 server, in its logging? "%u" gives me the uid provided by
the
client of course, but it would useful for my purposes to catch the
"destuser" in the same log line. 
 
The only way to get the proxy to log "destuser" at all, as far as I
can
figure out, is to enable "auth debug" - not something I want to do in
a
production environment.
 
Thanking-you,
Paul

Hi Timo

Thanks very much, hadn't finished my morning coffee and already a patch
:)

The patch does the trick:

- My dovecot.conf for the proxy:
  ...
  login_log_format_elements = pid=%p user=%u method=%m rsock=%r:%b
lsock=%l:%a proto=%s %c
  login_log_format = MYPROXY %s %$:
  ...
- gives me, via syslog:
Aug 14 10:14:03 withnail dovecot: imap-login: MYPROXY pid=6516,
user=pgamble at abc.co.za, method=PLAIN, rsock=127.0.0.1:48157,
lsock=127.0.0.1:1143, proto=IMAP, secured proxy(pgamble at abc.co.za):
started proxying to 127.0.0.1:143/pgamble*master:
Aug 14 10:26:02 withnail dovecot: pop3-login: MYPROXY pid=6514,
user=pgamble at abc.co.za, method=PLAIN, rsock=127.0.0.1:55991,
lsock=127.0.0.1:1110, proto=POP3, secured proxy(pgamble at abc.co.za):
started proxying to 127.0.0.1:110/pgamble*master:

This is just on a dev box, hence the odd IP's, log format, etc.

I'm using "master authentication" for the backend auth and so the
the
master user and separator character are imbedded in the backend user,
i.e. "client->proxy_user", ("pgamble*master" above) and
it would be
convenient to have them available separately, but I can live with it
as-is.

So...great stuff, thanks very much! What is your approach with regards
to incorporating these kinds of patches (in response to ad-hoc user
requests) into your main development tree? It would obviously be nice to
know that this will be incorporated at some point... Would it be
feasible to add a "config variable" for this (along the lines of %u,
%p,
%s, etc, etc)?

Regards,
Paul Gamble
