I have a problem with the opgrade of ZCS 6.0.8 on a debian etch machine.

Code:
Operations logged to /tmp/zmsetup.11102010-100658.log
Upgrading from  to 6.0.8_GA_2661
Stopping zimbra services...done.
Verifying /opt/zimbra/conf/my.cnf
Starting mysql...done.
I can't upgrade version

UPGRADE FAILED - exiting.
I note that zimbra can't determine the version of the current zimbra version.

Also when i try to get the status I see the following info

Code:
Unable to determine enabled services from ldap.
Unable to determine enabled services. Cache is out of date or doesn't exist.
The users are authenticated in Active Directory, so I hope the solution must be in that direction, but I can't be sure.

I tried many solutions posted in the forums but no one works for me.
