Upgraded to 10.9 and OS X Server 3.0.1, users cannot connect to home shares

Hello. I recenlty upgraded from Lion Server to Mavericks and Server OS X and users are now unable to access their home shares. When one attempts to afp to the server after connecting to my uni's VPN, the login box simply shakes and no connection is made.

Running Mac Mini with 10.9 and OS X Server 3.0.1 with home shares located on a Pegasus RAID array that worked fine under Lion Server. The upgrade seemed to go smoothly, as all accounts were intact and the settings were identical to the functional Lion Server settings. I have combed these forums trying to find a response that actually works for me, but was unable to locate a match that resulted in a working solution.

Here is a sample log when attempting to login:

When I first upgraded, I was able to connect via PC but not Mac (10.9) clients, so I tried creating a new account to attempt to ferret out the problem. When I created a new account in the Server.app connecting to an existing home share, I was still unable to connect to it remotely--Server.app threw the "Cannot authenticate connection..." error and closed. I then attempted to create a new user and new home share directory in Workgroup Manager and received an error stating the home directory could not be created (I forgot the actual verbiage, but I will replicate and post if needed). I tried simply adding the folder to the home shares folder, but I was still unable to connect via afp or smb.

Any suggestions are greatly appreciated, as I need to resolve this issue ASAP. Please let me know if any other information would be useful to diagnosing this issue.

Thanks!
