[horde] Login problem

[Antonio Esposito]

HI all!
I've downloaded the latest tarball version of horde, and after read and
check all the installation INSTALL file, my horde was go on-line. Now
the problem, when I write in my browser http://my.ip.address/horde I see
the login panel, then with a mail account in my box I write login (the
mail account) password (the password of mail account). But it stay in
login page. Someone can help me?
Best Regards.
Antonio
