To determine if these parameters are set to appropriate values, type the following command:
ldapsearch -b /base/ (&(icscalendarowned=*/user/*)(objectclass=icsCalendarUser))
/base/ is the LDAP base DN of the directory server where the user and resource data for Calendar Server is located.
/user/ is the value that an end user can enter in the Calendar Search dialog under the Subscribe option in Communications Express.
The LDAP server returns an error, if the nsSizeLimit or the nsLookthroughLimit parameter is not large enough.
Ensure that the value for nsSizeLimit parameter is large enough to return all the desired results, otherwise, data can get truncated, and no results will be displayed.
Ensure that the value for nsLookthroughLimit parameter is large enough to complete a search of all the users and resources in the LDAP directory. If possible set nsLookthroughLimit to -1. By doing this, no search limit is set for nsLookthroughLimit.
It is recommended that the User or Group and Address Book entries in LDAP are setup separately.
