Is there anyone using multiple IMAP servers with Horde4/IMP5?
I have to find a way to authenticate to the IMAP server with a bare
username, but store preferences in the Horde database with a domain/realm.

Is there a recommended way to replicate/replace the old "realm"
parameter in IMP5? I have 2 issues I am trying to solve:
1. I have 8 different IMAP servers. 2 of them are different IMAP
servers, but I want to share user preferences between them (we are
migrating slowly over time from an old IMAP server to a new IMAP server)
2. Username is not unique between all 8 IMAP servers, so in the
preferences backend (MySQL) I need to have a realm/domain appended to
the username. For example, pref_uid should contain "[email protected]"
instead of "morgan".
In IMP4, I used the realm parameter to accomplish both goals. I have
been reading the backends.php and hooks.php files, but I don't see how
to get a realm/domain appended to the pref_uid.
Preferences are stored by the current Horde username. This can be
altered from the authentication username by using the 'authusername'
hook.
Is the 'authusername' hook only in Horde or is it available in IMP as
well?
How can I determine which IMAP server the user selected from within the
'authusername' hook? Does $credentials['server'] contain it? Once I have
the server, can I access the backends.local.php $server['foo'] values?
I have been playing around with this some more. I found the $credentials
array passed to IMP's preauthenticate hook contains:
'password' => (the user's password)
'mode' => 'traditional'
'imp_server_key' => 'onid'
"onid" is the key in my backends.local.php file for one of my IMAP servers.
However, I can't seem to access the $servers array. I tried just logging
it:
Horde::logMessage("IMP Server Realm: " .
$servers[$credentials['imp_server_key']]['realm'], 'NOTICE');
Which produced an error in the log:
HORDE: [horde] PHP ERROR: Undefined variable: servers [pid 1217 on line
36 of "/var/www-test/horde/imp/config/hooks.php"]
I don't know enough about the structure of IMP. Is there a way to access
the $servers array or some API call I can make to access it?
My intention is to make the Horde ID be a fully-qualified name
([email protected]), then make an authusername hook to strip the domain off
for authentication.
Okay, after flailing around for an hour, I've discovered that I should be
using the 'authusername' hook, like Michael said. I tried playing with
preauthenticate and postauthenticate hooks, but that just left me unable to
login whenever I appended the realm.
If I hardcode a realm in authusername, I can make things work the way I want:
public function authusername($userId, $toHorde)
{
if ($toHorde) {
Horde::logMessage("toHorde userId: $userId", 'NOTICE');
return $userId . '@onid.orst.edu';
} else {
// strip the domain off
$userId = substr($userId, 0, strpos($userId, '@'));
Horde::logMessage("toHorde userId: $userId", 'NOTICE');
return $userId;
}
}
However, what I really need to do is lookup the realm on the fly. Is there
some session parameter I can use as a key to lookup the $servers entry?
I really need the ability to qualify usernames with realms!
Thanks,
Andy
