[xwiki-users] How to rename a user ?

Hello! i want to rename some users in a XWiki. Background is that I want to migrate to a LDAP user database. As I understood this operation is not supported straight forward by the GUI. See http://jira.xwiki.org/browse/XWIKI-3548. Has somebody an SQL statement to perform the necessary data manipulation on the database level ?
