thanks phoenix for your help!
I made the installation like wiki,
And i recieved an answer like
zmzimletctl deploy /opt/zimbra/zimlets/com_zimbra_bulkprovision.zip
I logged to zimbra admin 7071 to then use my brand new zimlet but it wasn't deployed. I went back to wiki and it says that for admin extension installation, you need to restart mailboxd, so i exe my command line
 INFO: Deploying on mydomain.com
 INFO: Deploy initiated. Check the server's mailbox.log for the status.
but it failed
$> su zimbra
$> zmmailboxd restart
zimbra@mydomain:/root$ zmmailboxd restart
zmmailboxd: command not found
