Summary: dovecot 2.0 breaks dovecotpw encryption

Also, dovecot 2.0 (which is nearing release, see
http://dovecot.org/list/dovecot-news/2010-July/000162.html) will break this
setting, because dovecotpw has been removed and its functionality
integrated in doveadm.

So the command to encrypt a password goes from
dovecotpw -s 'CRYPT-METHOD' to
doveadm pw -s 'CRYPT-METHOD'

Maybe something to look into for 2.3.2 :D~

Oh, nice - I like it when external programs come with incompatible changes
:-/ Well, at least it's a new major version ;-)

$CONF['dovecotpw'] = '/path/to/doveadm -pw'
could work... (untested, feedback welcome)

If this works, I'll add a comment to config.inc.php in the 2.3 branch.
(I'd like to avoid a bigger change in this branch.)

It doesn't work.

After a bit of tinkering, it appears that doveadm does a check on whether
it's stdin is a tty or not (It outputs "Fatal: stdin isn't a TTY")

Guess we can't fix this without "bigger changes". :(

Message:
A user comment on http://php.net/manual/en/function.proc-open.php (from
2007-12-27) suggests that using 'pty' might work.

Please open functions.inc.php, search for "$spec = array(" (around line
1213 in 2.3.1) and replace it (including the following 3 lines) with:

 $spec = array(
     0 => array('pty'),
     1 => array('pty'),
     2 => array('pty')
 );  
 
Does this help?

Otherwise we'll probably have to use "doveadm pw -p foobar" with the
password on the commandline. However I don't like this idea because the
password will be visible in the processlist for a short time then :-(
