I've got a big problem

[Loic BERARD]

Hello everybody,
I would be the happyest man in the world if someone could help me.
So here is my problem :
I am using imp-3.0 and horde-2.0.
When I put a .htaccess in my horde directory I can't arrive to the login
page, everything go into an infinite loop...WHY ?
Is it a bug ?
Can someone explain me how work horde/login.php , horde/imp/login.php,
and horde/imp/redirect.php, the loop seems to come between this three
files.

Help please help :)
