ERROR [http-8080-24] [atlassian.confluence.servlet.ConfluenceServletDispatcher] sendError Could not execute action
 -- url: /pages/getpagepermissions.action | userName: xxxxxx | referer: http://confluence.zzzzz.com/display/space_name/page_name
java.lang.IllegalArgumentException: No such user: [yyyyy]

原因

There are users in the content perm table that do not exist in the cwd_user table.  This is most likely due to the incorrect deletion of users.

ソリューション

Find those users that have orphaned permissions

SELECT *
FROM content_perm
WHERE username NOT IN (SELECT user_name FROM cwd_user)

Ensure that the users that appear in your list of results should re removed them. Make sure you have a backup of your database before you start removing things

1. Remove them a user at a time - Preferred solution

   DELETE FROM content_perm
   WHERE username = <user_name>

2. Remove Everything.

   DELETE
   FROM content_perm
   WHERE username NOT IN (SELECT user_name FROM cwd_user)

For good measure it is a good idea to flush your browser cache and perform a res-sync on your user directories.
