Grab patch from http://jira.atlassian.com/browse/CONF-9434
The attached atlassian-user JAR includes a fix for this issue in Confluence 2.5.6 and 2.5.7. To install it, please do the following:
- shut down Confluence
- put the attached JAR, 'atlassian-user-confluence-2.5.x-1.9.jar', into confluence/WEB-INF/lib/
- remove the old atlassian-user JAR from confluence/WEB-INF/lib/ (it should be called 'atlassian-user-1.5-stable-compatible-1.jar')
- start up Confluence again.
