Bitlocker Backup To AD

I'm having trouble getting my clients to backup the bitlocker info to AD. I've followed the Configuration Guide (we're running Win2k3R2 domain controllers) as well as the Testing steps detailed in the guide. I'm successfully able to backup TPM information, but the FVE information isn't even attempted to be backed up to AD. I've checked the GPO, and checked the registry on the client as well, and HKLMSOFTWAREPoliciesMicrosoftFVEActiveDirectoryBackup and RequireActiveDirectoryBackup are both set to 1.

It looks like those two GPO objects are being set, but not enforced. I think that because I don't have any 513 or 514 errors in the System Event Log (for FVE anyway - I see the 514 for the TPM backup), and I did a packet capture and don't see a conversation happening between the client and any of my DC's. Also, Bitlocker successfully encrypts the volume, which I thought it shouldn't do until it successfully backed up the recovery information to AD, and it's not there (I used a regular LDAP browser as well as the add-on for AD Users & Computers and the FVE entries are nowhere to be found).

I was able to replicate this on two Windows 7 Enterprise x64 clients. I'm at a loss at this point at even where else to look for hints of what's going on.
