FortiFone not displaying Directory

Hello, we recently upgraded our FortiVoice to 6.4.2 and the phones no longer display the directory. I see the phones get some informaiton on them about LDAP Directory, but this directory is not used when Dialing extensions or searching the directory. Is there any setting that needs to be configured to allow for this? The extension privilege does have access to search directory and you can see the directory from the web login, just not from the phone itself.
