Novell has discovered a serious NSS corruption issue with NetWare 6.5 SP4 when running the rebuild option. In certain cases the overflow beasts containing trustee or compression metadata may be truncated out of the NSS database causing the loss of trustees or even compressed files.
There is a tool being prepaired called FIXOVFT to help repair the trustee link to the overflow beast. Watch for the fix / patch soon. I'll post a link here on my blog site. There is discussion about removing NetWare 6.5 SP4 and re-releasing SP4 with the fixed rebuild option.
Loss of compressed files will have to be restored. Trustees will need to be recreated or restored from backup.
NetWare 6.5 SP4 was released August 30, 2005.
