      Work Description: zeroflag opened a new pull request, #640:
URL: https://github.com/apache/knox/pull/640

   ## What changes were proposed in this pull request?
   
   The `btoa` (third party) javascript functions can't base64 encode some of the special characters such as the letter `ë`. 
   We use this function to create the basic authorization header. If user's password contains an unsupported character the login will fail.
   
   
   ## How was this patch tested?
   
   I tested the new funciton manully:
   
   ```
   unicodeBase64Encode('árvíztűrő tükörfúrógép ë !#$%^&*()_!#@V')
   'w6FydsOtenTFsXLFkSB0w7xrw7ZyZsO6csOzZ8OpcCDDqyAhIyQlXiYqKClfISNAVg=='
   
   unicodeBase64Encode('阪熊奈岡鹿梨阜埼茨栃')
   '6Ziq54aK5aWI5bKh6bm/5qKo6Zic5Z+86Iyo5qCD'
   阪熊奈岡鹿梨阜埼茨栃
   ```
   The I decoded the result I got back the original string.
   
   The I changed sam's password in users.ldif:
   
   ```
   # entry for sample user sam
   dn: uid=sam,ou=people,dc=hadoop,dc=apache,dc=org
   objectclass:top
   objectclass:person
   objectclass:organizationalPerson
   objectclass:inetOrgPerson
   cn: sam
   sn: sam
   uid: sam
   userPassword: 阪熊奈岡鹿梨阜埼茨栃 árvíztűrő tükörfúrógép ë !#$%^&*()_!#@V
   ```
   
   Unfortunately the demo ldap server could not parse this password because it calls `Strings.toLowerCaseAscii(line)` on each line of the ldif file. After I temporary removed the toLowerCase I was able to start the demo ldap with this config.
   
   I check the login on the knox ui using the knoxsso topology and I was able to successfully login.

> E.g.: when there is a "ë" in the password the base64 encoder silently ignores the character.

> btoa('abcë')
> 'YWJj6w=='
> {code}
> The decoded version of 'YWJj6w==' is 'abc' without the 'ë'
