Interesting. I remember have case sensitivity problems ( among others )
when using 'net rpc vampire' with 3.0.1-rc-something.
Actually I had such a hard time that I decided to hold off until the
process went a little smoother.
Yeah I also remember hand-editing /etc/passwd entries ( sometimes
unsucessfully - I rooted some guy's account good ! ).
Have there been any bug fixes to the 'vampire' function since 3.0.1?
While I understand the cause of the case sensitivity problems, I think
this still needs more attention - perhaps all names should be forced to
lower case? Lets just say that my previous experience didn't exactly
inspire confidence in the system I was setting up - hence we are still
on an NT4 domain controller.
Anyway, since someone else had a 'very smooth' experience, maybe I was
partly to blame. I'll give it another go when I get more time.
