Add an Option NameCase that can be set to 'lower' or 'upper', which will convert REMOTE_USER to lower/uppercase. Any other string, as well as not setting the option, will leave REMOTE_USER alone.
(At least some versions of) Apache will always log APLOG_NOTICE, independent of LogLevel, which produces a lot of spam in error_log. Changed Log Level APLOG_NOTICE to APLOG_INFO to prevent this.
