[doc] Webmail Installation-help!

[Andy]

I am currently installing a mail server on my LINUX 7.3 machine.

I use qmail together with courier-imap and horde/imp in order to provide
webmail functions. I install qmail, courier-imap successfully and I have
tested the installation as well, it works fine!

After installation of horde and IMP, I find out that I cannot authenticate
throught the web interface. However, when I use the test.php provided by
IMP, I can log-in.

Please can anyone help me out?

Thanks!
