[imp] Weird problem with alternate login

[Rodrigo Borges Pereira]

Hello,

I'm trying to setup a customized login page for imp, but something weird
is happening..

Using just the basic custom_login.php as a template (modified as needed
of course), i login and then i get a "page not found". At this point,
the browser is showing "http://domain/horde/imp/redirect.php" as the
URL. If I hit refresh here, I get into my mailbox... Doesn't make much
sense to me. 

Any ideas on this? 

TIA
