... 17 moreThe 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
Set up Confluence and JIRA
Add Confluence as an application in JIRA's User Server configuration
Add the directory to Confluence. Select Read/Write in the options.
Add a user to JIRA
Sync the user to Confluence
In Confluence, add the user to another group
Sync with JIRA
Cause
Might be related to CONFSERVER-28194 - Confluence attempts to apply group memberships when synchronising from a remote directory even if they already exist, causing a duplicate key violation or CWD-3147 - If a user exists in two directories in an application, and is added to a group in one directory that it was already in the other, clients get duplicate key errors.
Workaround
Log in with an internal administrator account
Edit the properties of the directory
Set it to Read Only
Save and sync
Edit the directory again and set it back to Read/Write
Sync again
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.
