CQ5: “LDAPException: error result (4); Sizelimit exceeded” when synchronizing users

Issue

If you are using an LDAP connection with your CQ server you may notice that the LDAP users are not imported correctly to CQ with a warning similar to the following in the error.log:

09.11.2012 10:22:57.624 *WARN* POST /system/console/jmx/com.adobe.granite.ldap…DTools/op/syncAllUsers/ HTTP/1.1 com.day.crx.security.ldap.principals.LDAPPrincipalProvider Error finding user * com.day.crx.security.ldap.LDAPRepositoryException: LDAP error: com.day.ldap.LDAPException: error result (4); Sizelimit exceeded

09.11.2012 10:22:57.625 *INFO* POST /system/console/jmx/com.adobe.granite.ldap…Tools/op/syncAllUsers/ HTTP/1.1] com.day.crx.security.ldap.LDAPUserSync LDAP synchronization: 0 of 0 users synchronized in 0 seconds

Reason

This error is caused by your LDAP settings. In ActiveDirectory (AD), for example, there is a maxpagesize limit set to 1000 by default. This is the maximum number of results returned for any given LDAP query, including CQ user synchronization.  For more information see: http://support.microsoft.com/kb/315071?wa=wsignin1.0

Solution

You have a few options to avoid this problem:

  1. ask your LDAP administrator to increase the maxpagesize on your LDAP server
  2. use filters in your LDAP queries to reduce the number of LDAP entries returned so that you do not hit this limit
