[imp] initial page

[Hans Gerber]

hello,

Lately I have updated both horde from 2.2.1 to 2.2.5-cvs and
imp from 3.2 to 3.2.3-cvs. Everything is smooth and running.

There isI only  one thing left I can't figure out.

imp is setup to do the authentication stuff with
"horde/config/registry.php"
$this->registry['auth']['login'] = 'imp';
$this->registry['auth']['logout'] = 'imp';

also I set in horde/config/prefs.php:
$_prefs['initial_application'] = array(
    'value' => 'imp',
    'locked' => false,
    'shared' => true,
    'type' => 'select',


Problem:
after the login I always get a "portal-page"(?) of horde with all
mailboxex listed but not the usual view of imp.

I notice this URL:
http://mywebmail.somehost.de/horde/login.php?actionID=149
after succesfull login.

it used to be:
http://mywebmail.somehost.de/horde/imp/mailbox.php?mailbox=INBOX.keep&actionID=149
before.

That is what I have setup within imp.

Any clue where to look, what might go wrong?

Thx,
Hans
