[imp] imp with php4 ?

[Bongo Kader]

Helo,

I install php4; horde and imp3 on a woody.
All goes well; but when i want to access to the web page 
i have this error :

Warning: Access denied for user: 'hordemgr@localhost' (Using password: YES)
in /etc/horde/db_mysql.inc on line 73

Warning: Access denied for user: 'hordemgr@localhost' (Using password: YES)
in /etc/horde/db_mysql.inc on line 73

Warning: Access denied for user: 'hordemgr@localhost' (Using password: YES)
in /etc/horde/db_mysql.inc on line 73

Warning: Cannot add header information - headers already sent by (output
started at /etc/horde/db_mysql.inc:73) in /usr/share/horde/imp/mailbox.php3
on line 111

The mysql database work well (i test it with the imp parameters (user &
passwd).

Is imp3 work with php4 ?
I need help please
