You're getting "crickets" just like I did so far in looking for feedback on this product. I'm thinking that it is still too new and needs more loving care from vmware which I hope they will continue to do and not give up on it.
Have you tried the CLI to join your domain? I found that was successful but my network settings keep dropping off after reboots.
Try this if you haven't confirmed that your appliance is joined to the domain
/opt/likewise/bin/domainjoin-cli join domainfqdn domainadmin
