Using NetWare 6.5, in ConsoleOne, double click a user object and it shows the following error:
(Error -618) The server has detected an inconsistent database
Novell's support site has a page that might be helpful, click here.
If that advice doesn't help you (it didn't help me!) then restart the server! That solved it for me. After restarting the error didn't occur. But of course you should also ensure you run DSREPAIR until you get 0 (zero) errors.
