Server app v3.01 User Accounts password add/reset/editing functions greyed out

Question

I recently upgraded a Lion server to Mavericks with 1500 users and 450 clients on Xserve early2009 2.26Ghz Quad core Xeon 24GB RAM  32 TB Raid.
        All the upgrade went ok through 10.7 to 10.8 to 10.9 apart from having to rekerberise the realm to get users to log in from various 10.7,10.8,10.9x10) clients . I do not use Profile Manager as yet as I have had lots of faults on test networks etc so I continue to use Workgroup Manager 10.9 and Server app v3.01 now that Server Admin Tools has been discontinued.
        I have noticed however that all my users in Accounts/Server App are not editable such as password resets adding and deleting users etc. If you choose Edit User all the information shows but is greyed out for editing etc.
  I still use WorkGroup Manager for adding/editing users and changing passwords which still functions(thank goodness).
        Am I missing something in that I cant edit/add users because I upgraded from a previous directory and OS etc? Do I have to accept the server app wont edit/add users and stick with WGM? Or are there serious underlying faults with my  open directory?
         There are also lots of quirks in the File Sharing pane with users hanging on after logging out from clients and duplicates of log ins when they log in again. Today I restarted my server to update the Server app to 3.01 and i got a message saying 361 users were logged in although no users were showing in the File Sharing pane for about 12 hours! Obviously there is some problem with the termination of the log out process in AFP that doesnt take place. Since reboot this morning the memory usage has dramatically decreased so I am waiting to see if the errors return when we get a busy network situation later today.
Anyone had tthese problems or fixed the issues?

Just to update my post I referred to the the brilliant Krypted site to see if anything would help my situation and found this post on resetting the Server.app. I havent had time to try this yet but I'd like others to comment if they try it first:
"Unresponsive Server After Mavericks Upgrade? Reset Server App
The Server 3 app is great. But when you go making changes to some things, you’re just going to cause problems, sometimes something as simple as just upgrading to the latest and greatest version of Server… I know, you’ve been told that host name changes and IP changes are all kinds of OK at this point; “look, Charles, there’s a button!” Well, go ahead, click it. Don’t mind me, you might just be alright. But then again, you might not… And upgrades that use a migration wizard… Um, when it works it’s a thing of beauty. But when it doesn’t, you might be restoring some stuff from backup. But just before you do that restore, let’s try one more thing. Let’s try and rebuild some certificates and configuration settings that shouldn’t impact actual service operation. Let’s try to reset the Server app and let a fresh install of the Server see if it can fix issues.
Now, I want to be clear, this is the last resort before restoration. I’ve had a lot of luck with services remaining functional and preserving settings when I do this, but don’t expect that. Basically, we’re going to do what we looked at doing back in ’09 with AppleSetupDone but one designed just for servers, so the file is in the same place (/var/db) and called .ServerSetupDone. To remove it, close Server app and run the following command:
sudo rm /var/db/.ServerSetupDone
Once removed, open the Server app again and then let the Server app run as though it’s new. Cruft, begone!"
