Group and User Management Related Changes Made in LDAP are Not Reflected in Confluence
Symptoms
It takes 24 hours for changes such as group renaming in the LDAP directory to show in Confluence. The changes are visible in Crowd almost instantaneously (as configured) but Confluence doesn't seem to react to those changes.
Flushing Confluence's cache from "Administration->Cache Statistics->Flush All" console, appears to make those changes visible in Confluence immediately.
Cause
Logs report the following error:

Resolution
The suggested step to copy CROWD/client/conf/crowd-ehcache.xml to CONFLUENCE/confluence/WEB-INF/classes/crowd-ehcache.xml has not been completed successfully, and the above file is still using Confluence's default crowd-encache.xml not the one copied over from Crowd as recommended in point 3 in this document.
Ensure that the above file has been copied across correctly and then restart the applications.
