After getting some help with setting my hostname correctly, I was able to install Zimbra 4.5 on Ubuntu Server 6.06. I set my admin password and saved my configuration.

I tried to log in at the web page..I enter and my password. I get the following error:

An unknown application error has occurred. Please correct any errors and retry. If the problem persists, please contact your System Administrator. (INVALID_PDU)

I thought maybe my password could be bad so I tried to reset it to something simple, like "test".

root@campeemail:/opt/zimbra/bin# pwd
root@campeemail:/opt/zimbra/bin# ./zmprov sp test

I try to login again. Same error What did I do wrong?
