Deleted user is not anonymized in metadata set

Problem

SINCE CONFLUENCE 6.13

Since Confluence 6.13 when a user is deleted the anonymization process is started automatically by Confluence. But the "user" field type in metadata seems not to get anonymized because there is no automatic reindex started. Therefore you spaces or pages with this user in the metadata can be found after deleting the user.

Solution

If you delete a user and have a field type "user" active in a metadata set, please rebuild the index. Afterwards you will not find documents with the old user name any more.
