Re: OS vs. Directory Service
Ah, the memories. -xk2'ing servers and such. Just had a virtual eDirectory 8.8 server eat its own face last weekend (not the directory's fault - a disk error led to OS issues). One of my fondest memories of NDS was documenting all the error codes because Novell wouldn't. That was tons of fun - NetWare's kernel debugger was very interesting to tinker in.
Lots of fond memories teaching troubleshooting and eDir internals over the years. I've seen all sorts of weird issues over the years - even communications errors causing stuck INHIBIT_MOVE obits in single-server trees (which I still haven't managed to understand how that happened - had to be database corruption of some sort).
