Hi Jay,

many thanks for your response.

I have a similar set of scripts currently they only run wbinfo -t and a
script to check net ads testjoin is sane. They don't catch this. I was
thinking about processing the log with something like swatch but it's a
kludge. I would be interested in seeing your sanity checks if you don't
mind?

Cheers,

Matt
