Description

As per the current design NetScaler will send the encoding type as UTF-8 in 401 request which is affecting IE browser if user password contains Swedish characters (å,ä,ö). UTF-8 encoding works fine with Chrome not with IE and Firefox
 
In Failing case
FireFox and IE: Basic YmRuOkhlam9jaEjl

  • UTF-8 cannot decode this correctly
  • ISO-8859-1 or Windows-1252 decodes correctly to bdn:HejochHå 
    In Working case:
    Chrome: Authorization:Basic YmRuOkhlam9jaEjDpQ==
    UTF-8 decodes to bdn:HejochHå
