Error using IMAP for AUTH

[Nicola Foggi]

Hello Everyone:

I'm currently using:

Horde 1.3.4
IMP (Latest CVS)
PHP 4.0.5

I've set my horde.php file to use "imap" as it's auth driver, and defined the servers, however I always get a 

"Call to a member function on a non-object in /export/home/www/test/horde/login.php on line 39"

whenever I try to logon... ANY help would be appreciated!

I can logon to IMP directly, but whenever using the HORDE logon, it fails out!

Let me know!

Thanks!

Nicola Foggi
