[Exim] server_condition in SMTP AUTH

Hi all,


I've a Debian Potato 2.2 system with exim installed and I'd
like to use SMTP AUTH for my clients.

My problem is with the server_condition, according the config
example C034, the line bellow:

server_condition = "${if and {{!eq{$2}{}}{!eq{$3}{}} \
{crypteq{$3}{${extract{2}{:} \
{${lookup{$2}lsearch{/etc/passwd}{$value}{*:*}}}}}}}{1}{0}}"

is used for non-shadow passwd. I changed it to /etc/shadow, because
I use shadowed passwd. Well, no success.

Could anybody send me a server_condition example for shadowed passwd ?
Please, send a cc to fabio@???.

Thanks all,
        Fabio
