KIRK 6000 Active Directory access page size limit

Connect with big Active Directory fails error message in the log file:

"ldap_search_ext_s: ldap://customer.domain.tld: Size limit exceeded" - this occurs when the number of all elements in the base OU exceeds the AD page size limit (1000 by default). In this case KIRK have to use paged search: is it possible to use paged search and how to do so?

Re: KIRK 6000 Active Directory access page size limit

We have seen this before, as you might know our KIRK Wireless server can handle up to 40.000 entries in the LDAP internally, but if you haven’t (have not) increased you windows LDAP (user query return size) size you will have a problem if the number of returned item from the LDAP is over 1000. Microsoft LDAP have a query limit is set to 1000 objects per request.


The KWS6000 is asking for the complete LDAP and not just 1000 at one time, so you need to increase your windows LDAP size limit.

This is the error you get a error from the LDAP server that size limit is exceeded on the returned items from the server- Not the KWS6000


Link to how to increase the number is returned items:

A new feature has been implemented in the Q4 2012 software.

to be released in October 2012


The corporate phonebook now supports LDAP paged searches, it retrieves 500 records at a time.
