[horde] Redirecting with the vinfo_hook

[carlos maca]

Hi, i had made some changers, i use the auth with aplications to IMP,
everything was okay. But, i had change my login process to accept the vinfo
function hook, so in the login page, appears the domain fixed, so the use
can login with only the username. but, after you click on connect, the
process looks like it took the authentication, but it has a failure to
redirect the page. and a page apperas saying: The page in not redirecting
correctly, it´s says that "the metod that the server is redirecting dont
permit the complete of the process."

i think that the redirect problem is because it is not seeing the horde
directory. When i disable the vinfo hookk in the im/config/con.php, and
keeps the function in hooks.php,  i can login on horde, but i cant see the
imp, its ask me to re-login. Any idea, ?? i think the problem is that it
cant see the horde directory, how can i fix this ?
