[horde] Please Help...I'm at my wit's end!!!

[root]

Hey All,

First allow me to be upfront and tell you that I am not very experienced 
in PHP or MySQL.

With that in mind, I have followed all directions in setting up Horde/IMP 
and the Horde MySQL database.

I have opted to use the IMP login screen for logging in and not the Horde 
login screen so that my users only login once.

I am using pop3:110 and pop3/ssl:995.  If I telnet to port 110, I can 
check my mail by using the pop3 terminal commands.

I run the Imp/test.php script from the web, everything looks fine.  It 
says Imp is running fine.  I'm running 3.2.1 Imp on Horde 2.2.1.

Here's the problem...On the test page, I've tried typing in the 
domainname, the host.domainname, localhost, the physical ip, etc. Then, 
I'd type in pop3 on port 110 and pop3/ssl on 995 with my username and 
password.  The test.php returns Bool{false}.

I can't login to Imp/index.php because it says that my username and 
password are incorrect.  I've tried logging in as a personal account, and 
as root.

Again, I don't know much about this stuff...Am I suppose to link my 
etc/passwd file to Horde somehow so that it knows the users?  Did I just 
plain out miss something?  Any ideas/help are much appreciated!

Thank you,
Joshua Davis
