I have read through the docs at http://www.zimbra.com/community/documentation.html and during install on my Centos 4.3 box I was never asked to set an admin password.
So I can't login to the web admin page. I have tried to set the password using the command 'zmprov'; however I still can't login.
Here is what I did
zmprov sp email@example.com password
ERROR: account.NO_SUCH_ACCOUNT (no such account: firstname.lastname@example.org)
[zimbra@lilac ~]$ zmprov sp admin password
ERROR: account.NO_SUCH_ACCOUNT (no such account: admin)
[zimbra@lilac ~]$ zmprov ca admin password
ERROR: service.INVALID_REQUEST (invalid request: must be valid email address: admin)
[zimbra@lilac ~]$ zmprov ca email@example.com password
The when I try to log into the admin I get the message "User does not have administrator rights".
By the way the user can log into the front end.
I can't think how to add or modify the admin user if this does not work.
