Open Directory / Workgroup Manager woes

Folks,

I’m experiencing random changes to my Open Directory user accounts that have me pretty concerned. First, here are the offending systems’ specs:

#1 Xserve G5 2×2.0GHz, 10.5.4 running AFP / Open Directory
#2 Xserve G5 2×2.3 GHz, 10.4.11 acting as storage via AFP

Now and then I receive a user complaint stating she’s able to login on the network but can’t write to her personal folder. Upon inspection I find a mismatch between the UserID on #2 and the UserID in Workgroup Manager. Changing the Workgroup Manager UserID to match that on #2 will fix the problem and it never comes up again for the offending user.

Within the next 48 hours I will have another user at my desk with the same problem. I can’t find any links or similarities between the users experiencing this problem. Both systems above have more than enough disk space and are not max’ed out re: system resources being used. And this happened before I upgraded #1 to 10.5.4 from 10.4.11.

Sometimes the UserID that shows up in Workgroup Manager is a 11 or 12 character string of numbers, sometimes a more reasonable looking 4 or 5 character string of number UserID.

Please ask any questions about system config, specs, etc.

Thanks for your attention,
Steven
