I spent a few hours today dealing with Hyper - V and NetSUS. Apparently you can't import the OVA into HyperV. I did a clean install of Ubuntu 14 and ran the NetSUS installer. Everything worked great except the AFP mounts for Shadow files were not being created correctly. Looking at the logs and verbose boot I could see an err 39. I also couldn't afp mount through Finder using the afpuser account. Apparently it a bug in Ubuntu 14. I found this on a message board that fixed it and everything worked!!
It's a bug in libpam-smbpass. You can get rid of it, the only thing it does is that it forces sync between the samba and unix password on login:
sudo apt-get remove libpam-smbpasssudo service netatalk restart
