Hmm, I have some problems with realization of authentication throw dovecot
socket.

I've wrote such script:

#!/usr/bin/perl

$login = "test";
$passwd = "test";

#utf8::encode($login);           # I don't know are we really need it
#utf8::encode($passwd);

my $service = "ejabberd";
my $timeout = 1;
my $socket = '/var/spool/postfix/private/auth-client';

my $sock = new IO::Socket::UNIX(Type => SOCK_STREAM, Peer => $socket) or
  die "Can't open socket.";


my $sel = new IO::Select($sock);
while (1) {
$sel->can_read($timeout) or last;
 defined recv($sock, my $buf, 256, 0) or warn 'Error while reading
response';
print $buf;
}

send($sock,"VERSION\t1\t0\nCPID\t$$\n",0) or
die "Can't write to $socket";

 my $base64 = encode_base64("\0$login\0$passwd");
$sock->send("AUTH\t1\tPLAIN\tservice=$service\tsecured\tresp=$base64\n") or
die "Can't write to $socket";

my $i = 10;
while ($i--) {
 $sel->can_read($timeout) or last; # "Timed out while waiting for response";
defined recv($sock, my $buf, 256, 0) or warn 'Error while reading response';
 print $buf;
}

And has such log:

# ./test.pl
MECH PLAIN plaintext
MECH LOGIN plaintext
VERSION 1 0
SPID 26023
CUID 1818
DONE

So dovecot doesn't answer anything after AUTH command. May be
http://wiki.dovecot.org/Authentication%20Protocol is not fully describe auth
protocol?
