Confluence Sync to JIRA Remote User Dir fails

[Nathan McC]

Trying to get Confluence talking to JIRA remote directory, but the user sync was working is now failing with the following error in the logs. No idea whats causing this. Stash is also setup to use the JIRA user directory and it works fine. 

Using Postgres SQL as the database.

Hi Nathan. Did you manage to resolve this issue? I am experiencing the exact same thing..

Hi Nathan,

org.springframework.dao.IncorrectResultSizeDataAccessException: query did not return a unique result: 2

Looks like 2 user records are returned where 1 is expected.

This is for MySQL: https://confluence.atlassian.com/pages/viewpage.action?pageId=254739329 and it says to do not use case insensitive collate. I have no experience with PostgreSQL so I am not sure if that's a case for you.

This article is about removing duplicates: https://confluence.atlassian.com/display/CONFKB/User+Login+Renders+Error+-+Query+Did+Not+Return+a+Unique+Result
