The nsslapd-sizelimit and nsLookthroughLimit attributes in your LDAP directory server configuration must be large enough so that searches complete properly. If nsSizeLimit is not large enough, truncation can occur and no results will be displayed. If nsLookthroughLimit is not large enough the search may not complete.
This section covers the following topics:
To determine if these attributes are set to appropriate values, try the following command:
ldapsearch -b "base" "(&(icscalendarowned=*user*)(objectclass=icsCalendarUser))"
where base is the LDAP base DN of the directory server where the user and resource data for Calendar Server is located, and user is the value that an end user can enter in the search dialog in the user interface.
If the LDAP server returns an error, the nsSizeLimit or the nsLookthroughLimit parameters might not be large enough.
The DN for these attributes is:
dn: cn=config,cn=ldbm databases,cn=plug ins,cn=config
Use ldapmodify to dynamically set the value of nsLookthroughLimit.
You do not have to stop and restart Directory Server to change this attribute.
The default value is 5000. You might want to increase this value if searches are not reporting results. However, this could slow down the LDAP server.
It is possible to set the limit to -1, which causes no limit to be used. However, do this with caution as it could conceivably cause the system to hang.
If you want to set nsslapd-sizelimit to a higher value, you must perform the following steps:
Stop the Directory Server.
Edit the dse.ldif file.
Restart the Directory Server.
