Hi,
I couldn't resolve my problem using a virtualbox, so I decided to restart the work on my host machine (within the binary solution works fine). First, I remove the binary solution, then I applied this tutorial exactly
Ubuntu Hardy - Setup Build Environment
And at the end I find the same problem (the configuration of openldap)!
Comparing this install with the binary one, I find that in my install (from source) the /opt/zimbra/conf contain only one file (dspam.conf) and only one directory (spamassassin), but in the /conf of the binary install (I saved all the zimbra directory before removing the binary installation) I find 148 files and 4 directories!!!
Is this normal?

I can't find the problem anywhere!
For the host `hostname` gives me this:
monaco.*****.net is an alias for
www.*****.net.
www.*****.net has address 19*.***.*.**6
Sorry for the *** but I can't put the exact adresse of a company as it appear for security reasons.

Thanks in advance
