Major Description
The current Dn and filter handling is overly restrictive in that all non-ascii characters are quoted using the \NN syntax. This is probably due to rfc 2253 being unclear about the fact that multibyte UTF-8 encoded values can be used, but this iss further clarified in rfc 4514 which superceeds 2253. The application of unrequired quoting makes debugging / reading logs much harder then it should be, as it requires manual calculations rather then just setting the file encoding on your log file / IDE windows to being UTF-8.
I have attached a patch file with the required updates to code and unit tests under /shared/ldap (some problems i had noted with earlier AD version due to unspecified encoding when converting bytes to / from Strings had already been tidied up in AD 1.5.4).
