Workaround

If you've installed Confluence version 3.5.1 or later, skip to step #4 below. Otherwise, if you're running Confluence 3.5:

1. Download the attached migratelocalgroups.jsp
2. Copy it to the <confluence install>/confluence/admin folder
3. Start up Confluence and log in as a local user with administrator privileges
4. Visit http://<confluence url>/admin/migratelocalgroups.jsp
5. Follow the instructions on the page

If you are not sure what your local admin user is, please execute the following database query:

select * from CWD_USER where id in (select child_user_id from CWD_MEMBERSHIP where parent_id = (select id from CWD_GROUP where group_name = 'confluence-administrators' and directory_id = (select id from cwd_directory where directory_type = 'INTERNAL')));
