Tuning LDAP Related Configuration Parameters

This section describes the tuning you can perform on Directory Server to enhance performance.

Setting the nsSizeLimit and nsLookthroughLimit Parameters for Users and Address Book

It is important that the nsSizeLimit and nsLookthroughLimit parameters in User or Group LDAP directory and Address Book server configuration is large enough for searches to be completed properly.

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.

Follow these guidelines to reset nsSizeLimit or the nsLookthroughLimit parameters:

Note –

It is recommended that the User or Group and Address Book entries in LDAP are setup separately.
