{noformat} h2. Known issues The fix for this issue adds further diagnostics that will (in much more limited circumstances) trigger more null pointer exceptions that will abort synchronisation. These are described in CONF-23102, and fixed in Confluence 3.5.12 or higher. For this reason, *the recommended fix is to upgrade to 3.5.12 or higher*. h2. Patch Attached to CONF-22342 is an updated version of [atlassian-embedded-crowd-hibernate2 jar|https://jira.atlassian.com/secure/attachment/48380/atlassian-embedded-crowd-hibernate2-1.2.9-m3.jar], to patch this issue. When patched, transactions will now correctly rollback, and log the records that were in error. It is known to work in Confluence 3.5.4 and 3.5.5, and might work in earlier versions, but these have not been tested, nor should they require it unless they are patching CONF-22342. It is not needed in Confluence 3.5.6, as that version already contains this fix. h3. Installation To install the patch: # Stop Confluence # Move the old atlassian-embedded-crowd-hibernate2 jar out of {{<confluence install dir>/confluence/WEB-INF/lib}} # Copy the new jar into the same directory # Start Confluence

    We are using read-only LDAP with jira and confluence, same configuration is used for jira & confluence, but unfortunately confluence have problem with synchronization.
