I am trying to rename a Zimbra installation from "zimbra" to "zimbra.openforce.com" using the zmsetservername command. I want to have a FQDN zmhostname to make amavis and friends happy.
Unfortunately it seems that the command has some problem with the ldap database.
The output of zmsetservername ends with:

adding new entry "uid=zimbra.openforce.com,cn=admins,cn=zimbra.open force.com"

ldapadd: Invalid syntax (21)
additional info: objectClass: value #0 invalid per syntax
adding new entry "cn=zimbra.openforce.com"

adding new entry "uid=zimbra.openforce.com,cn=admins,cn=zimbra.open force.com"

When I restart zimbra, all processes start fine, exect the mailbox daemon. Looking at /opt/zimbra/log/mailbox.log I see

2009-10-06 17:27:53,317 FATAL [main] [] system - Could not find an LDAP entry fo
r server 'zimbra.openforce.com'

I had a look at the content of the ldap database, but well there quite a few with the string zimbra inside ...
Which one do I have to change to make the mailbox server happy ?
