[imp] Missing 'initial_page' definition for IMP

[Miroslaw Jaworski]

Recently in one of my latest Horde/IMP installations a customer wanted
his own login/logout screen.

Versions used:
horde-2.1
imp-3.1
turba-1.1

I found nice IMP options designed to do such a customization.
horde/imp/config/conf.php excerpt:
$conf['user']['alternate_login'] = ''
$conf['user']['redirect_on_logout'] = ''

Both were changed to an URL with customized page.

Problem:
--------
After login, switching from IMP to other application ( in this installation 
only one additional application was present - turba ) and choosing IMP back
( by using menu's 'Mail' item ), we get an customized login page instead 
of mailbox content view.

Description:
------------
$registry->getInitialPage($app)

function is used for determining a link to the application. It returns a
'horde/imp' path. 

/horde/imp/index.php does redirection to a /horde/imp/redirect.php,
/horde/imp/redirect.php does redirection to a /horde/imp/login.php,
/horde/imp/login.php does redirection to alternate login page, which is 
bad.

Fix:
----
Probably same problem was ancountered in horde ( i presume that's why 
horde's 'initial page' paramater is set and is equal to 'login.php ). 

Fixing the problem either needs some playing with params passed between
all redirection scripts ( harder ) or just setting IMP's 'initial page' 
paramater in horde/registry ( easier ):
-----------------------
$this->applications['imp'] = array(
    'fileroot' => dirname(__FILE__) . '/../imp',
    'webroot' => $this->applications['horde']['webroot'] . '/imp',
+    'initial_page' => 'login.php',
    'icon' => $this->applications['horde']['webroot'] . '/imp/graphics/imp.gif',
    'name' => _("Mail"),
    'allow_guests' => false,
    'show' => true
);

After that change $registry->getInitialPage($app) function will return
'horde/imp/login.php' which will result in proper functioning of customized
IMP.

I admit, i didn't checked if it's fixed in the HEAD versions.

Regards
