To enable calendar searches to look at the LDAP directory first, and the calendar database second, perform the following steps:
Edit the service.calendarsearch.ldap parameter in the ics.conf file, setting the parameter to “yes”, which is the default, as shown below:
service.calendarsearch.ldap="yes"
Restart Calendar Services as follows:
start-cal
If you are allowing anonymous access to public calendars, you might prefer to disable calendar searches from looking at LDAP. In fact, Communications Express expects the parameter value to be “no”.
