pfSense

I have an existing Active Directory domain and I recently added another AD Server in my existing domain. Existing servers are Windows 2008 R2 and my new one is Windows 2012 R2. When I change my existing working LDAP configuration in pfSense to point to the 2012 R2 DC and press the button for select authentication containers I get an error "Could not connect to the LDAP server. Please check your LDAP configuration." If then go back to the Settings tab and go to the authentication server drop down and press the save and test button I get this.

Attempting connection to
192.168.200.27
OK
Attempting bind to
192.168.200.27
OK
Attempting to fetch Organizational Units from
192.168.200.27
failed

pfSense is able to connect and bind hjust fine but whatever the fetching on Organization units is it fails on. I cant find anything else in the logs to indicate where the issues is. If I change nothing else but change the IP to the old server (192.168.200.26) everything works. Am i doing something wrong or is this an incompatibility with Windows 2012 R2?
