Zimbra password issue

Hi,

I've just installed Zimbra Network Edition on my Elitebook just for test purposes. However, when i try to do anything as a zimbra user and tries to do a command like "zmprov" or any other things i just get asked for a Zimbra password. I have tried running as root but it still keeps asking me for a password i haven't set. And when i try to reset the admin password this comes up:

zimbra@zimbra:~$ zmprov sp admin@zimbra.empir.se admin
[] INFO: I/O exception (java.net.ConnectException) caught when processing request: Connection refused
[] INFO: Retrying request
ERROR: zclient.IO_ERROR (invoke Connection refused, server: localhost) (cause: java.net.ConnectException Connection refused)

When i check the status this is what i get.

zimbra@zimbra:~$ zmcontrol start
Host localhost
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn't exist.
zimbra@zimbra:~$

Anyone got a clue what may cause this? I'm doing my internship and i've just graduated high school and i'm studying for a year to be an technical college graduate.
So you can see i'm quite new to all this.
