------------------
Increment minor version as we changed the default password hash to a new one
that isn't supported by earlier versions of TLDAP.
Added
~~~~~
* Supports ldap3 2.2.3
Changed
~~~~~~~
* Rewrote test cases. Now smaller in scope for what each test covers. Needs
more work for queries.
Fixed
~~~~~
* Fixed bug setting primary group if primary group already set.
* Allow clearing/setting primary group if current value invalid.
* Fix incorrect DN calculated in cached data after move.
Security
~~~~~~~~
* Use sha512_crypt by default for passwords instead of ldap_salted_sha1. We
still support salted ldap_salted_sha1 for existing passwords.
