When i try to upgrade to 4.5.2 it say it dosent find ldap.

zimbra-ldap...NOT FOUND
zimbra-logger...FOUND zimbra-logger-4.5.1_GA_660.DEBIAN3.1
zimbra-mta...FOUND zimbra-mta-4.5.1_GA_660.DEBIAN3.1
zimbra-snmp...FOUND zimbra-snmp-4.5.1_GA_660.DEBIAN3.1
zimbra-store...FOUND zimbra-store-4.5.1_GA_660.DEBIAN3.1

zimbra-spell...FOUND zimbra-spell-4.5.1_GA_660.DEBIAN3.1
zimbra-core...FOUND zimbra-core-4.5.1_GA_660.DEBIAN3.1

Im not sure where i should start to search for the problem. Zimbra runs without no problem, and the ldap seems to run. zmcontrol status says the following
Host XX
antispam Running
antivirus Running
ldap Running
logger Running
mailbox Running
mta Running
snmp Running
spell Running

Could there be a problem with the permission? Anyone have an idea?
