I have downloaded and installed the OS X version of Network Edition Trial. The installation went smooth. When I log into the https admin site, the admin user I configured is not allowing me to log in.

After some forum reading, I executed this command to change the password;

mail:~ zimbra$ zmprov setpassword admin@mail.domain.com mypassword
ERROR: account.NO_SUCH_ACCOUNT (no such account: admin@mail.domain.com)

Here is the info for my server:

Store configuration

1) Status: Enabled
2) Create Admin User: yes
3) Admin user to create: admin@mail.domain.com
4) Admin Password set

Any advice is greatly appreciated!
