Pro přístup je třeba použít LDAPS.
When setting password, it needs to be UTF-16LE and Base64 encoded. In Java, it could be done with:
String source = "\"car\"";
String utf16base64 = new String(Base64.getEncoder().encode(source.getBytes("UTF-16LE")));
UTF-16LE has to be used, UTF-16 is not enough.
Online tool can be used – http://www5.rptea.com/base64/ (select UTF-16).
