where are the authentication settings for dovecot/imap stored?

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  on a lenny system, recently, someone else went in and reconfigured
the authentication used for the mail system, and mail is currently
working fine.  i now want to add a new email client (IMP, part of the
horde framework) but i obviously need to configure it to match
whatever the new mail authentication protocol is.  where can i find
that?

  for those who've actually worked with horde and IMP, here's what
looks like the relevant snippet from the horde/imp/config/servers.php
file:

$servers['imap'] = array(
    'name' => 'IMAP Server',
    'server' => 'localhost',
    'hordeauth' => false,
    'protocol' => 'imap/notls',
    'port' => 143,
    'folders' => '',
    'namespace' => '',
    'maildomain' => '[deleted].com',
    'smtphost' => 'localhost',
    'realm' => '',
    'preferred' => '',
    'dotfiles' => false,
    'hierarchies' => array()
);

  i have good reason to believe that those settings are no longer
correct, i just need to know how to figure out what they *should* be
on this system.
