[imp] Horde/IMP Login Problem

[Kalle Foggy]

Hi all,

since a required server reboot, it's not possible to login to the 
Horde/IMP Interface.
When correct username/password is entered it takes about four minutes 
till the message "login failed" is shown.

The Horde Log shows only:

Dec 09 13:08:21 HORDE [error] [imp] FAILED LOGIN for Info [XX.XX.XX.XX] 
to {localhost:143 [imap/notls]} [pid 17774 on line 139 of 
"/var/www/horde/imp/lib/Auth/imp.php"]

In the meantime I changed the config files with the one's out from the 
backup, but it's still the same problem.

I use Horde 3.2.1 with IMP 4.2.
PHP Version: 5.2.0-8+etch13
Apache2

The Horde System Capabilities Test shows that everything is ok.
It seems that Horde could not reach the mysql Database, but MySQL is 
running.

Thanks for any help you may be able to provide.

Best regards

Markus
