CALDAV not adding accounts in iPhone

Question

Hello!
We have a private server here (we're a small company) and have just upgraded to Snow Leopard on it and all of our individual machines. Additionally, everyone's iPhones are running 3.0 or higher, which supports CALDAV integration (or, so we've been led to believe) that we were really excited to finally et to implement. But we are having major issues.
When I go to: (in the phone) settings>mail, contacts, calendars>add account>other>add caldav account and then proceed to input all of our calendar information using the same information we used to setup our desktop calendars so we know the information is valid (we all have individual ical accounts on the server) then hit 'next' I keep (and so does everybody else) getting an error message saying "caldav account verification failed". EVERY TIME.
We know for a fact that we're inputting the correct information because we'll put in the same information on iCal on a laptop when adding a new account, and it works just fine.
(Back to the iPhone) Even though the verification failed, it will still give me the option to save, so when I tap that, I get another message saying "This account may not be able to sync calendars. Are you sure you want to save?". That defeats the purpose of trying to add a caldav account to my iphone, but whatever, I'll hit save.
Then, after the account is added, a dialogue box keeps popping up saying "Password Incorrect" and asking me to input it again. I do and wait a second and then it keeps doing it over and over and over again regardless of my having already inputted the correct password every time.
Can somebody help me with this?
