ComputerGroups not accessible after upgrade to 10.5

I finally upgraded my 10.4.11 server (intel xserve) to 10.5.6 server today. Everything went well, except now in WGManager, I have *no* computer groups (not even the default ones). I can see my old 10.4 computer lists no problem (if I use the inspector).

When I try to create a new group, I get an error:

Got Unexpected Error
Error of type eDSOperationFailed (-14483) on line 1139 of /SourceCache/WorkgroupManager/WorkgroupManager-319.2.2/PMMUGMainView.mm

I tried restoring from a pre-10.5 open directory archive, as well as deleting all of my computer lists and computers, and I still get the same problem.

So I go to dscl to see what’s up…

Everything seems fine here as well, except inside ComputerGroups, when I do an ls I get:

/LDAPv3/127.0.0.1/ComputerGroups > ls
ls: DS error: eDSOperationFailed
<dscl_cmd> DS Error: -14483 (eDSOperationFailed)

I can’t seem to find *any* info on what’s happening here, all I get from internet searches is what the error means: “Specified operation failed during authentication.”

Any ideas at all? Unfortunately, this is of course a production server with a few hundred managed computers… I think they will continue to work as computer lists, but I have to use WGManager from 10.4 to make changes or additions to the management, and I’m not able to include the management options that persuaded me to upgrade in the first place!

Is there any way to replace the computer groups part of the schema with the default one and continue from there?

Thanks! Craig
