i'm testing ZCA version to replace our kerio solution. Everything works at least as good but not iCal delegations.

I'm using the following filters:
LDAP filter: (|(cn=%s*)(sn=%s*)(gn=%s*)(mail=%s*))
Autocomplete filter : (|(uid=%s*)(givenname=%s*)(mail=%s*))

iCal invitations are working fine, but the "delegatoins" tab in iCal stays empty, also if i add it manually.
"enable delegation for Apple iCal CalDAV" is checked.

Any ideas? Please, for further infos ask if needed.
