11753,3.0 upgrader needs to lowercase usernames,Denis-de-Bernardy,,"I'm opening this in advance so we don't forget. ms-default-filters.php has the following filter:

{{{
add_action ( 'sanitize_user', 'strtolower_usernames', 10, 3 );
}}}

after upgrading to 3.0, some users may end up wanting to turn their existing sites in a Multisite install. In the event this happens, we should:

 - fix the strtolower_usernames() function if needed (see #11751)
 - lowercase all usernames accordingly
 - double check that previous logins still work (they should work fine, see #5472)",defect (bug),closed,normal,3.0,General,3.0,major,fixed,multisite,
