In case you want to export all users let's say to migrate to another system you can change the limitation to a value which allows you to export all users. You can do this by doing following:
Go to the server where your WCI LDAP Directory service runs. The limitation is configured in the configuration.xml file, which you can find under: %WCI_INSTALL_PATH%/settings/.
Inside the folder open the configuration.xml file and search for the component: aluidirectory:backend:
Change the value to a number which will allows you to export all users from the database. Make sure that you restart the LDAP Directory Service after you make the change.
IMPORTANT: After you finish with the export, change back to the original value and restart the service again.
