> In isLoginAttempt method in BasicHttpAuthenticationFilter class fails if used
> in any locale other than English. This happens because at the line String
> authzScheme = getAuthzScheme().toLowerCase(); , the toLowerCase methods takes
> i18n into consideration. If the locale of the host is Turkish the string
> "BASIC" becomes "basıc" but not "basic" (there is the letter "ı" -lowercase i
> without the dot- in Turkish) So the comparison returns false. The method
> fails.
> The solution is pretty easy:
> The two lines of the method "isLoginAttempt" in BasicHttpAuthenticationFilter
> class should be changed as below to make sure it works always the same:
> protected boolean isLoginAttempt(String authzHeader) {
> String authzScheme = getAuthzScheme().toLowerCase(Locale.ENGLISH);
> return
> authzHeader.toLowerCase(Locale.ENGLISH).startsWith(authzScheme);
> }
