At some point the User Directory in Confluence stops synchronising. There is a 'Synchronisation Failed' error in the admin interface:

 

The following appears in the atlassian-confluence.log:

The tested case was JIRA 5.2.4 as a User Directory, with Confluence 4.3.7 as the 'client'. This error may occur in numerous other configurations.

Steps to Reproduce

  1. Set up Confluence and JIRA
  2. Add Confluence as an application in JIRA's User Server configuration
  3. Add the directory to Confluence. Select Read/Write in the options.
  4. Add a user to JIRA
  5. Sync the user to Confluence
  6. In Confluence, add the user to another group
  7. Sync with JIRA

原因

Might be related to  CONF-28194 - Getting issue details... STATUS  or  CWD-3147 - Getting issue details... STATUS

 

回避策

  1. Log in with an internal administrator account
  2. Edit the properties of the directory
  3. Set it to Read Only
  4. Save and sync
  5. Edit the directory again and set it back to Read/Write
  6. Sync again
  7. Observe that the group membership has synced to JIRA, and there are no more failures

If this doesn't work, you can disable the current directory and set up another one, after making the user's membership changes in JIRA if required.
