Our work server was working fine and now its not!


I propergated permissions and restarted the server.


Now all the staff users and groups are missing. Ths is a disaster it means no one can log into the system.


I've got everything one logging in using the admin account temporarily as this works.


I'm not sure if it's related but there also seems to be a problewm with many KEXT files.


I'm about to re-install the combo update for 10.6.8 in hope it fixes trhe problem.


In the mean time, any ideas for how to fix this?


Many thanks

    First thing I would try is a Repair Permissions in Disk Utility.

    I've run into this issue as well. My client was using the Snow Leopard Apple Server on a Mac Mini. We checked the UPS units and they were solid with voltage regulation in place, but users and groups were randomly missing. We would re-add them and others would go missing.


    We upgraded to Lion and Lion Server, but the problem persists. I've run disk permissions on the internal raid, which was a bit of an exercise in itself since Disk Utility is broken on the Mac Mini with a raid drive, but terminal was able to fix any issues. So far it seems to be working, but the problem seems random.


    What's surprising is I have found next to no other reports of a similar issue. At this point, it appears to be a hardware failure of some sort. There doesn't seem to be a software answer if the disk permissions fix doesn't help it. I'm sitting on pins and needles at this point hoping this works.


    Did the repair permissions fix your problem, Chris?

    Do not ask me why, but I did the following and it works:


    1. Erase the Server application using AppCleaner.
    2. Restarted the server
    3. Install the Server application from the App Store
    4. After the installation, turn Open Directory Off and On in the Server application.
    5. If the does the same to you, all my users and groups appeared back.


    Good luck with this very impredictibile piece of software...

    backup the OD

    export users, groups computers etc

    demote to stand alone

    promote to OD master


    importing your OD backup may introduce the problem again or it may not

    but you'll have users , groups, computers, etc complete with passwords


    importing just the users, groups computers etc won't import any dodgy OD backup

    but you'll loose user password


    you could also image the system beforehand , in case it all goes wrong
