Problem Ldap and Multiple OU on Windows

Hi I have Installed Wildfired and is Working Fine With Windows Server. I have multiple OUs but Only Users OU can LogIn on Serer. When other on different OU user try to LogIn ocurr this error " Error Trying to Authenticate you. Either you used the Wrong Password or this Account is already in use by someone else". If I move the user to OU users can LogIn Succesfully. This is my configuration File of Ldap

Any Ideas ? Thanks

Only objects in the baseDN and objects below it in the tree will be recognized. If the other OUs are not below the baseDN, they will not be viewed by WF. also change your baseDN to OU=Users, DC=xxxx,DC=com,DC=ar.
