Redmine

Hi guys.
I have a big problem with LDAP+Remine authorisation.

So
Server LDAP - Win 2008 Server

Redmine
Bitnami Redmine 2.4.3

and
Redmine 2.4.2

Environment:
Redmine version 2.4.2.devel
Ruby version 1.9.3-p194 (2012-04-20) [x86_64-linux]
Rails version 3.2.16
Environment production
Database adapter Mysql2
SCM:
Git 1.7.10.4
Filesystem
Redmine plugins:
ekanban 0.0.1
redmine_ckeditor 1.0.4
redmine_code_review 0.6.2
redmine_contacts 3.2.3-light
redmine_contacts_helpdesk 2.2.2-pro
redmine_favorite_projects 1.0.1
redmine_issue_checklist 2.0.5
redmine_ldap_sync 2.0.3.devel.g7f1c325e31
redmine_people 0.1.6
redmine_zenedit 0.0.1

Steps to reproduce

On Windows side
1. Go to Active directory/Users
2. Create new User (for example TEST)

On Redmine side
1. Go to LDAP
2. Fill
Name: windows auth
PC: 100.100.00.100 (for example)
Port: 389
Login: INT\admin
Pass: 12345678
BaseDN: CN=Users, DC=INT, DC=domain, DC=com (and many more variants)

After this steps i make test and this test complete.

Okay.
First problem. User TEST does not login into Redmine
Second problem. I add this TEST user into Redmine manually. And after this user TEST does not login into Redmine. Again.
Third problem. I make group on the Windows side and certainly, i don't see this group in Redmine. After this i add some users to this group and make this group in Redmine. Result - user doesnt add to this group.

What i doing wrong? Why LDAP doesn't working?
