Ldap configuration failed

Hi ,
I am new in Suite CRM and just install SuiteCRM 7.10.10 on Windows Server 2012 with SQL Server.
Normal admin user can access and no issue. B-) B-) B-)

But I want to use it with our active directory. I have the issue and it shows [color=#ff0000]Invalid credentials[/color] :woohoo: :woohoo: :woohoo:

Anyone can help me this?
Thanks in advance. :slight_smile: :slight_smile: :slight_smile:
